उत्तर १
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 
उत्तर २
`""_13"Al"` = 2,8,3 ∴ Lewis symbol = 
, `"Al"^(3+) "ions" = ["Al"]^(3+)`.
