Question

how is periodicity of properties dependent upon number of proton in an atom

Answer 1

Answer:

he observed that the frequency of the emitted characteristic X-ray of different elements is proportional to square root of atomic number . where v is the frequency Z is the atomic number

Answer 2

Answer:

since, Number of protons =number of electrons.

and The protons in the atom of any element gives the Atomic number .And by modern periodic table The properties of the element are the period function of their atomic number .

Due to this periodicity of properties dependent upon number of proton in an atom.
