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

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
What is Periodic table of elements?Definition: Periodic table of elements is the row wise and column wise arrangement of chemical elements in the increasing order of their atomic number. This arrangement of elements is done in such a way that the elements lying in the same column have similar properties. This is the short and … Read more
The Periodic table elements are arranged in the increasing order of their atomic number. The arrangement of elements in the Periodic table starts from the very first top left corner. The first element with atomic number 1 (i.e hydrogen) is placed in the first cell, then gradually the elements with atomic number 2, 3, 4 upto 118, … Read more
So you have seen the above image by now, right? Let me explain the above image in brief. There is a girl named Neea. So remember the word “I M NEEA”. Where, I = Ionization energy M = Metallic character N = Nonmetallic character E = Electronegativity E = Electron affinity A = Atomic size … Read more
OMG !! Alkali Metals in water produce flames? Yes… Alkali metals are so reactive that they even produce flames or even explode when they come in contact with water. But hold on… A simple question is; Why do alkali metals react with water? Well, there are many reasons behind the reactivity of alkali metals, like; … Read more
