Question

Name the following
A. Alkali metal with smallest atom.​

Answer 1

Answer:

O2-is the smallest oxygen alkali metals -potassium ,ribidium ,and cesium react with oxygen to give up metal superoxide

Answer 2

The alkali metal with smallest atom is the Sodium.

• The alkali metals are situated in the group one of the modern periodic table. ( hydrogen is excluded here)

• And,the atomic radius increases when we move down in a group in the modern periodic table.

• So,the topmost element (excluding hydrogen) in the group one will be the alkali metal with smallest atomic radius which is basically sodium.
