An ionic compound will be formed by the combination of one of the following pairs of elements. This pair of elements is:
(a) Chlorine and calcium
(b) Calcium and sodium
(c) Sulphur and carbon
(d) Chlorine and fluorine
1. Correct option is (A) Calcium and Chlorine.
2. This is because, an ionic bond is formed between a pair where one is electropositive (calcium) and other is electronegative (Chlorine).
3. All other do not have this combination.
