Write Lewis symbols for the following atoms and ions: Al and Al3+
Al and Al3+
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
`""_13Al` = 2,8,3 ∴ Lewis symbol = , `Al^(3+) "ions" = [Al]^(3+)`
