Introduction to Mendeleev Periodic Table

Dmitri Ivanovich Mendeléev, a Russian chemist, was the most important contributor to the early development of the periodic table. Many periodic tables were made but the most important one was the Mendeleev periodic table.

In 1869, after the rejection of Newlands Octave Law, Mendeleev Periodic table came into the picture. In Mendeleev’s periodic table, elements were arranged on the basis of the fundamental property, atomic mass, and chemical properties. During Mendeleev’s work, only 63 elements were known. After studying the properties of every element, Mendeleev found that the properties of elements were related to atomic mass in a periodic way. He arranged the elements such that elements with similar properties fell into the same vertical columns of the periodic table.

Mendeleev Periodic Table

Answer 2

Hey there!

- Mendeleev's periodic law states that physical and chemical properties of elements are periodic function of their atomic masses.

- He arranged the elements in increasing order of their atomic masses and was the first person to give all the elements known at that time.

- The zero period was not discovered at that time. Mendeleev's periodic table had 63 elements.

- He also left some spaces in the periodic table so that the elements can be placed which would be discovered later on.
