Question

Write a short note on ' Mendeleev 's Periodic law '?

Answer 1

❤️_______________________❤️


❤️ In 1869, Dmitri Mendeleev and Lothar Meyer individually came up with their own periodic law "when the elements are arranged in order of increasing atomic mass, certain sets of properties recur periodically."

❤️ Mendeleev realized that the physical and chemical properties of elements were related to their atomic mass in a 'periodic' way, and arranged them so that groups of elementswith similar properties fell into vertical columns in his 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.
