Explanation:

Aluminum (Al) has an atomic number of 13. Its electron configuration is \(1s^{2}2s^{2}2p^{6}3s^{2}3p^{1}\). To achieve a stable electron configuration (similar to the noble gas neon, which has 10 electrons), aluminum loses 3 electrons. When an atom loses electrons, it forms a positively - charged ion. So, the charge on an aluminum ion is \(+ 3\), not \(-3\).

Answer:

B. False
