Q3

(i) Electropositive nature of the element(s) increases down the group and decreases across the period
(ii) Electronegativity of the element decreases down the group and increases across the period
(iii) Atomic size increases down the group and decreases across a period (left to right)
(iv) Metallic character increases down the group and decreases across a period.
