Which statement has the fewest valence electrons available for bonding? Iodine.

Aluminum.

Carbon.

Nitrogen.

Aluminium has the fewest valence electrons available for bonding.

As we go across the groups from left to right, we have the following numbers of valence electron.

• Group 13: Al = 3

• Group 14: C = 4

• Group 15: N = 5

• Group 17: Cl = 7

Thus, Al has the fewest valence electrons available for bonding.
