Question

Name two other elements belonging to the same family as Calcium.

Answer 1

Alkaline Earth metals:

1. Alkaline earth metals i.e., group 2 elements form bases when dissolved in water.
2. They all have similar chemical and physical properties. Like most of them under normal conditions are shiny silvery white colored solids and they are highly reactive metals.
3. Their valency is 2, as they have 2 electrons in their outermost shell which they easily donate to form positive ions and attain noble gas configuration and become stable.
4. They all are highly reactive metals, as their Ionization potential is very low, and could easily lose their electrons to form ionic bonds.
5. Hence, Calcium belongs to the group 2 and two more elements from this group would be Magnesium $\left({}_{12}\mathrm{Mg}\right)$ and Barium $\left({}_{56}\mathrm{Ba}\right).$
