Write Lewis symbols for the following atoms and ions: Al and Al3+

Solution 1

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 

Solution 2

`""_13Al` = 2,8,3 ∴ Lewis symbol = , `Al^(3+) "ions" = [Al]^(3+)` 

  Is there an error in this question or solution?
