Answer:

The number of atoms in the outermost shell  

Explanation:

For example, the electron shells in the alkali metals contain the following numbers of electrons:

 Li: 2, 1

Na: 2, 8, 1

 K: 2, 8, 8, 1

They all have one electron in their outermost shell, and they have similar chemical properties.

Answer:

Magnesium and calcium belong to the second group i. e. alkaline earth metals. They are known as earth metals because they are extracted from the earth. They are very reactive elements. Their reactivity increases when we go from top to bottom because the outermost electrons goes farther from the nucleus i. e. atomic radius increases so less energy is needed for its removal.
