When we go from left to right1) valency first increases then after 4 decreases.
2)atomic size decreases
3)ionization potential increases.
4)electronegativity increases
when we go down a group :-
1)valency remains same
2)atomic size increases
3)ionization potential decreases
4)electronegativity decreases
