Answer 1

By considering their position in ‘periodic table’ amongst the following elements Ga is said to have the maximum metallic property.

Explanation:

• The metallic property of the elements of the periodic table decreases when we move across the group.

• Whereas it increases when we go down the group, as we go down the ‘number of electrons’ increases and thereby their distance from the ‘nucleus increases’.

• This increase causes them to shed more electrons and thereby have a greater electropositive or the metallic character.
