Answer:
A. I and F
Explanation:
The two element pair that will form covalent bonds in a compound are I and F.
A covalent bond is a bond type formed between two atoms of similar electronegativity difference. In fact, the electronegativity difference between the two atoms must be very small for covalency for occur.
- Therefore such bonds are notable between non-metals.
- From the choices given, I and F are the only non-metallic pair.
- Therefore, they will form a covalent bond.
Covalent bonds involves sharing of the valence electrons between two or more atoms to attain stability.
Metals are electropositive will not readily form covalent bonds.
