Question
Use Lewis symbols to show electron transfer between the following atoms to form cations and anions:
Al and N
Advertisements
Solution 1
The electronic configurations of Al and N are as follows:
Al: 2, 8, 3
N: 2, 5
Nitrogen is three electrons short of the nearest noble gas (Neon), whereas aluminium has three electrons more than Neon. Hence, the electron transference can be shown as:
