(a) K and S: 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: (b) Ca and O: The...

Hence, the electron transfer takes place as: (c) Al and N: 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: read less
