Question

how many valence electrons does aluminum (al) have available for bonding?
1
2
3
4

Explanation:

Aluminum (Al) is in group 13 of the periodic table. The number of valence electrons for main - group elements is equal to their group number (for groups 1 - 2 and 13 - 18). Group 13 elements have 3 valence electrons. So aluminum, being a group 13 element, has 3 valence electrons available for bonding.

Answer:

3 (corresponding to the option "3")
