Question

in the modern periodic table electronic configuration is related to the number of elements present in the periods. How?​

Answer 1

Answer:

valence electrons increase as we go right in the periods in M.P.T

Explanation:

The structure of atom is related to the modern periodic table. the electronic configuration is related to the number of electrons in the M.T.P as:

one valence electron is added to the valence shell as we go right in the period. For example, sodium has 1 valence electron and its electronic configuration is 2,8,1 but as we move across the period valence electrons increase and at the last in the inert gas column 18, the octet gets full, here in the inert gas is Argon whose electronic configuration is 2,8,8.
