Question

mendeleev periodic law short note

Answer 1

Also called Mendeleev's law. (originally) the statement that the chemical and physical properties of the elements recur periodically when the elements are arranged in the order of their atomic weights. There are afew elements still missing, according to the periodic lawwhich has been so valuable in chemistry.

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.
