Answer 2

Answer:

Mendeleev’s Periodic Law states that the properties of elements are the periodic function of their relative atomic masses

Explanation:

Explanation of Mendeleev’s Periodic Table:

Elements are arranged in the periodic table in the increasing order of their relative atomic masses.

Mendeleev divided his periodic table in eight groups and seven periods.

Groups from I to VII are meant for normal elements and group VIII is for transition elements.

Groups from I to VII have been divided in two sub groups, while group VIII is meant for three elements.

Periods from 4th to 7th have been divided in two series: 1st series and 2nd series.

Elements having similar properties have been kept in the same group. For example; lithium, potassium, rubidium, etc. are in 1st group
