Question

Sodium chloride is called electrovalent compound but ammonia is called covalent compound why

Answer 1

Answer:

as sodium has a strong force of attraction between their molecules the sodium chloride is a stable compound

(ammonia is called covlent)

it is because both nitrogen and hydrogen share their electrons so as to complete their outermost shell to form a stable covlent compound NH3 nitrogen has 5 valence electrons and need 3 more to complete it's outer most shell. as ammonia as a loan pair also it makes it a electron rich compound

Answer 2

Answer:

sodium chloride is called electrovalent compound because it is formed by transfer of electrons between atoms but ammonia is called covalent compound because it is form by sharing of electron theory between atom
