valence electrons -Group....the v.electrons remain constant whereas in a perion the valence electrons gradually increase by one unit
valency-valency remains constant in a group but in a period....it increases up to 4 and then decreases to 0
atomic size-size increases down the group whereas in a period size decreases as we move from left to right
metallic character-it increases as me go down a group but in a period m.c decreases as we move across a period
non-metallic character-decreases in a group but increases in a period
