Henry Mosley investigated the frequency of certain characteristic X -ray emitted by different element available during that time .
he observed that the frequency of the emitted characteristic X-ray of different elements is proportional to square root of atomic number .
e.g root v=K1 (Z-K2)
where v is the frequency Z is the atomic number .
hence, according to above explanation we can say that periodicity of elements is depend upon atomic number of its
