In which part of a group would you separately expect the elements to have:
(a) the greatest metallic character?
(b) the largest atomic size ?
a) At the bottom of the group ( example: Cesium - Group 1 (Alkali Metal) (b) At the bottom of the group.
Give scientific reasons:
1. Atomic size increases down the group.
2. Metallic character decreases from left to right in a period.
3. Elements in the same group show same valency.
