In terms of electronic configuration what does elements of given period and a group have in common?

$\large\purple{Answer}$

◇In a period, all elements have equal number of shells.

◇ In a group, all elements have equal number of electrons in the outermost shell.

Answer 2

In general, the elements belonging to a group have the same number of valence electrons . ... In general, the elements belonging to a period do not have same valency but their valence shell remains the same.

The elements of a given period have

same number of shell and a group have

same number of valence electrons in

common.
