The Periodic table or periodic table of elements printable is the arrangement of 118 chemical elements in a tabular form according to their atomic numbers, electron configuration, and recurring chemical properties. This arrangement represents periodic trends which show element which has same behavior together. In general, all elements within one row are metals on the left and all non-metals are on the right side. The rows of the table represent period and the column represents groups.
All elements are arranged from top to bottom and left to right according to increasing atomic numbers. The period number of an element represents the highest energy level that electron possess in that element in a dormant state. Element that occupies the same column on the periodic table have same valence electron configuration and they behave in a similar manner

Dimitri Mendeleev was a Russian chemist and inventor who is known as the father of periodic table in the year 1868-1870 Mendeleev wrote a book on chemistry titled as principles of chemistry which was a significant find as there were no books at that time in Russia. First of all, he wrote all the elements in a card according to their increasing atomic weight. This is the time when he noticed that certain elements are appearing regularly after working continuously for three days he arranged all the elements according to their atomic weight and valence. The most important aspect of the periodic table made by Mendeleev was that he left space for elements which were not discovered yet but he also predicted the properties of five of these elements and their compounds.
Ways of reading periodic table are as follows as periodic table contains very important information and it is necessary to read it correctly
- Atomic number- the atomic number of an element signifies the number of protons in an atom. The number of protons decides which element it is and what chemical properties will it posses
- Atomic symbol- the abbreviation used to represent any element is called the atomic symbol for e.g. c for carbon, h for hydrogen etc.
- Atomic weight- atomic weight of an element is the average mass of an element in atomic mass unit. Individual atoms are always having an integer number of atomic mass units. however if you have noticed that the atomic mass on the periodic table is represented as decimal number because it is the average of the various isotopes of an element. The number of neutrons present in an element can be found out by subtracting the number of protons from the atomic mass.
Periodic Table with Charges
The most commonly used periodic table is the table with the charges because it helps in predicting various compounds and its chemical reactions. The periodic table trends to predict the most common element charges. Group 1 which consists of alkali metals carry a +1 charge. Group 2 consists of alkaline earths which carry a charge of +2. Group 7 consists of halogens which carry a charge of -1and group 8 consists of noble gases which carry a 0 charge. The metal ions may have other charges or oxidation states. If we take an example then copper usually has a +1 or +2 valence while iron has +2 or +3 oxidation state.
Dynamic Periodic Table
Dynamic periodic table is web based application which is very helpful for chemistry enthusiasts. This application represents the elements in a more interactive form thus you can select one or more elements to see a list of compounds that can be formed with the combination of different elements. The dynamic table has other very important uses like you can see a element in its naturally occurring state and by clicking on any of the elements you can view that elements article on Wikipedia you can also see nos of electrons an element has and can view the table in wide layout form.
The dynamic periodic table has various other features like it can give you detailed information about each and every element like nos of electrons present in outer most orbit of an element. The orbital tab found on the Tab will help you to group the elements into 4 major groups S,P,D,F. therefore we can conclude that dynamic periodic table is a very interactive periodic table and impressive learning tool
Blank Periodic Table
Blank periodic table is a table which is used for practice purposes it is basically a blank table which you need to fill by yourself by memorising the periodic table therefore it tests one knowledge of the different elements there atomic weights, atomic number and valences so that you can easily place every element in the correct order and place. Periodic table for kids and other periodic tables are one and the same thing.
A periodic table is called periodic because all the elements in the periodic table are arranged in periods and cycles. Each horizontal row is called a period and there are total 8 periods. The first one is short and only contains 2 elements hydrogen and helium. The sixth period has 32 elements. Each element in the left most period has one electron in the outer shell and the right most period has a full shell. The groups in the periodic table are considered as columns and here are 18 columns in aperiodic table and each group has different properties
One example of a group in a periodic table is the 18th group which consists of noble or inert gases which have their outer shell full of electrons thus making them very stable i.e. they do not react with other metals another example which you can take is that of alkali metals as they only one electron in their outer shell thus making them highly reactive
Some fun facts about periodic table are as follows-
- Carbon is the most unique element as it is known for the formation of over 10 million compounds and researchers have also found out that carbon is the element necessary for existence for life
- Francium is the most rarest element to be ever found it is only available a few ounces only at a given time
- The only letter which is not available in the periodic table is the letter j
- The country Argentina is named after the element silver(Ag) which is argentum in Latin.
Periodic Table with Electronegativity
Electronegativity is the opposite of electro positivity which is a measure of an elements ability to donate electrons thus electronegativity is a property by which an element tend to loose their electrons. Electronegativity depends upon the atomic number of the electron and the distance at which the the valence electrons of the element resides in the charged nucleus.
If we take into account the first three rows of the periodic table it contains all the elements which are important for life, for example, the first-row elements helium and hydrogen will place their electron in the shell 1n. The second-row elements like lithium will start to fill their electrons in the shell 2n. Likewise, the third-row elements will start to fill the shell 3n. basically, the nos of valence electrons in an element is same as the column number and it increases from left to right within a row. Thus the group number is the measure of how reactive an element is.
Periodic Table with Mass
Periodic table with mass is the arrangement of elements in respect to their masses for example hydrogen has a atomic mass of 1.0079 which is the least among all the elements present in the periodic table therefore it is placed at the first place and the rest of the elements are placed after hydrogen with respect to their atomic weight
Periodic table metals
The elements in the periodic table can be divided into 3 categories
- Metals – they are good conductors of heat are malleable, ductile ,shiny and there are very few electrons in the outer energy level
- Non metals- they are poor conductors of heat non ductile nor malleable, not shiny and complete sets of electrons are found in the outermost shell
- Metalloids- they are the elements which posses both the properties of metals and non metals and are also called semiconductors
The metals present in the periodic table can further be subdivided into groups like group 1 is alkali metals, group 2 is alkaline earth metals, group 3-12 is a group of transitional metals all other groups are non-metals or metalloids
Periodic Table Orbitals
Periodic table orbitals can be better explained with the help of bohr model. The most early model of the atom was made by a Danish scientist niels bohr(1885-1962). Bohr model generally explains that the atom as the central nucleus containing neutrons and protons and electrons in the circular shell around it at a specific distance which is just like planets orbiting the sun. every electron has a different energy level. The shells which are closer to the nucleus are lower in energy level than the shells which are farther from the nucleus.
Every shell is assigned a number and symbol n for example the shell closest to the nucleus has a number 1n and in order to move between the shells the electron must absorb or release certain amount of energy which should be correspondent to the difference in energy between the shells for example if a electron absorbs energy from the photon then it will become exited and tend to move towards a higher energy level on the other hand if the electron drops back to the lower energy level then it will release certain amount of energy generally in the form of heat.
Bohr model explains the reactivity and chemical bonding of various elements but it is not able to explain that how electrons are distributed in space around the nucleus. Generally the electrons don’t circle the nucleus but spend most of their time in complex shaped regions around the nucleus known as electron orbitals. We can calculate mathematically the volume of space in which the electron spend its most of the time. The high probability region where the electron is most likely to be found is termed or called as orbitals
Printable Table Trends
The periodic table is called the periodic table not just because it is a tabular arrangement of elements but it reflects the periodic trends of the elements.
The following table shows trends of six different physical properties of the elements which are
- Atomic radius
- Electron affinity
- Ionisation energy
- Metallic and non-metallic character
Atomic radius is the ½ the distance between 2 identical atoms touching each other
Atomic radius increases as you move across the periodic table from right to left
And it decreases the other way around.
As we move across the periodic table from right to left each element will gain one more electron and one more proton. The electron then forms shells and are attracted towards the positively charged nucleus which pulls the shells closer to the centre which makes the atom smaller by the addition of each proton .
Electron affinity is the strength or ability of an atom to accept electrons.it is measured in terms of energy change in the atom as electron is added in the gaseous state
Electron affinity increases when you move from left to right
And electron affinity decreases when you move down the table
Electronegativity is the measurement of attraction between the atoms nucleus and electrons in a chemical bond generally it means that higher the electronegativity the stronger will be the force of attraction between bonded electrons and its nucleus.
- Electronegativity increases as we move across the table from left to right
- Electronegativity decreases as we move down the table
Ionisation energy is the energy required to remove an electron from a gaseous atom. The tighter the nucleus holds the electron more energy is required to remove an electron.
