Question

The highly metallic element has the configuration of 2,8,2.

• A. True
• B. False

Answer 1

The correct option is B False

The highly metallic element has the configuration of $2,8,2$ is false.

Metallic character is nothing but the loss of electrons readily and this character is shown by group $1$ elements.

The metallic character increases as we move down a group due to the fact that there is an increase in the distance between the nucleus and the valence electrons as well as the atomic radius increases.

1. The highly metallic elements belong to group $1$, also known as the alkali metals.
2. The alkali metals have a single valence electron.
3. Francium is the most metallic among the group $1$ elements, due it's position at the bottom-left of the periodic table.
4. Its configuration is given by $(2,8,18,32,18,8,1)$.

Hence, the given statement is false.
