Answer #1

answer : gallium , indium, thallium

Explanation :

these are the same group of aluminium. so these exhibit properties most similiar to aluminium.

these all are 3rd group elements:

1) boron (B)

2) aluminum (Al),

3) gallium (Ga),

4) indium (In),

5) thallium (Tl).

Aluminum, gallium, indium, and thallium have three electrons in their outermost shell a full s orbital and one electron in the p orbital.

with the valence electron configuration ns2np1.

The elments of the boron family adopts oxidation states +3 or +1.
