Question
Use Lewis symbols to show electron transfer between the following atoms to form cations and anions:
Ca and O
Advertisements
Solution 1
Ca and O:
The electronic configurations of Ca and O are as follows:
Ca: 2, 8, 8, 2
O: 2, 6
Oxygen requires two electrons more to complete its octet, whereas calcium has two electrons more than the nearest noble gas i.e., Argon. Hence, the electron transfer takes place as:
Solution 2
