Question

What is covalent bond? Explain the formation of Ammonia molecule by the covalent bond, with the help of a diagram.

Answer 1

✨ ANSWER ✨

⏩the chemical bond formed by the sharing of electron between two atom is known as a covalent bond. It is form when both the reactant atoms need electron to achieve inert gas electron arrangement. ⏪


✨ FORMATION OF AMMONIA, NH3 ✨

⏩each hydrogen atom needs one more electron to complete its valence energy shell. The nitrogen atom needs 3 more electron to complete its valence energy shell. therefore three pairs of electrons must be shared between the four atoms involved.⏪
