Question

A covalent bond is formed by____.

• A. Complete transfer of electrons.
• B. One sided sharing of electron.
• C. Mutual sharing of electron.
• D. By donating a lone pair of electron.

Answer 1

The correct option is C

Mutual sharing of electron.

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outermost (valence) electrons, atoms can fill up their outer electron shell and gain stability. Nonmetals will readily form covalent bonds with other nonmetals in order to obtain stability, and can form anywhere between one to three covalent bonds with other nonmetals depending on how many valence electrons they possess.
