The groups in the Periodic table are also called Families because; Explanation: All the elements lying in the same groups have the same number of valence electrons. Let me explain with an example. Example 1: The elements of group 1 have 1 valence electron. In other words, all the group 1 elements have 1 electron … Read more
The reason why there are 18 groups in the Periodic table is mentioned below. Explanation: All the elements found in nature have the outermost electrons between 1 to 8. But the question is; From where does this number 8 come from? The answer is, 2 electrons from s-orbitals and 6 electrons from p-orbitals. s-orbitals can … Read more
The reason why there are 7 periods in the Periodic table is mentioned below: (Note: Right now, there are 7 periods in the Periodic table. In future, there may be more than 7 periods in the Periodic table after the discovery of new elements.) Let me explain all these things to you in a simple … Read more
The reasons why periodic table is divided into blocks are given below: I know you haven’t understood these above reasons. So I have explained them below one by one. Reason #1: Because blocks represent the orbitals (or subshells) in which the valence electrons are present First of all you might know that there are 4 … Read more
The Periodic table is divided into groups for the following reasons; This was the overview. But I have given a plain english explanation of the above points. (See below). Explore our New Interactive Periodic Table with Rotating Bohr Models Access detailed info on all elements: atomic mass, electron configurations, charges, and more. View rotating Bohr … Read more
The First Periodic table was arranged in the increasing order of the atomic masses of elements. This was the first and very important arrangement created by Dmitri Mendeleev in the year 1869.Many chemists considered this as a very important classification. I know you can’t read anything from the above image. But this is the real picture … Read more
Here is a SUPER easy Explanation + Comparison on Mendeleev and Moseley Periodic table. In fact, I will also show you the old age original picture of Periodic systems which was published by Mendeleev in the year 1869. So let’s finish this very quickly. Mendeleev’s Periodic System I know you can’t read anything from this … Read more
History of Periodic table:It was not the one person (Dimitri Mendeleev) behind the discovery of Periodic table. But it was the combined efforts of many chemists for the invention of Periodic table.The chemists who invented Periodic table are listed below. Hold on… I’ll tell you the complete History of Periodic table starting from 1789 to 1913. … Read more
