How many valence electrons does aluminum (Al) have available for bonding?

The number of valence electrons that Aluminium (Al) have for bonding are three (3) valence electrons

Explanation

aluminium is in atomic number 13 which means it has 13 electrons in its atom. Aluminium electronic configuration is therefore 2.8.3 or [Ne] 3s^2 3P1. From electronic configuration aluminium has three valence electron that is the three electron in the last subshell of aluminium.

Aluminum has 3 valence electrons
