Question
Write Lewis symbols for the following atoms and ions: Al and $\text{Al}^{3+}$
✓
Answer
Al and $\text{Al}^{3+}$
The number of valence electrons in aluminium is 3.
The Lewis dot symbol of aluminium (Al) is:
The tripositive charge on a species infers that it has donated its three electrons. Hence, the Lewis dot symbol is. $[\text{Al}]^{3+}$
