(a) Electropositive nature of the element(s) increases down the group

1.	(a) Electropositive nature of the element(s) increases down the group and decreases across the period (b) Electronegativity of the element decreases down the group and increases across the period (c) Atomic size increases down the group and decreases across a period (left to right) (d) Metallic character increases down the group and decreases across a period.On the basis of the above trends of the Periodic Table, answer the following about the elements with atomic numbers 3 to 9. (a) Name the most electropositive element among them (b) Name the most electronegative element (c) Name the element with the smallest atomic size (d) Name the element which is a metalloid (e) Name the element which shows maximum valency
Answer» (a) Electropositive nature of the element(s) increases down the group and decreases across the period. (b) Electronegativity of the element decreases down the group and increases across the period (c) Atomic size increases down the group and decreases across a period (left to right) (d) Metallic character increases down the group and decreases across a period. Lithium is the most electropositive element . Fluorine is the most electronegative element Fluorine is the element with smallest atomic size among the given elements Boron e) Carbon is the element which shows maximum valency.
