Question
Use Lewis symbols to show electron transfer between the following atoms to form cations and anions:-
K and S
Advertisements
Solution 1
The electronic configurations of K and S are as follows:
K: 2, 8, 8, 1
S: 2, 8, 6
Sulphur (S) requires 2 more electrons to complete its octet. Potassium (K) requires one electron more than the nearest noble gas i.e., Argon. Hence, the electron transfer can be shown as:
