Question

Which phrase best describes a covalent bond?
Gaining protons
Losing electrons
Sharing of protons
Sharing of electrons

Answer 1

Answer: The correct answer is sharing of electrons.

Explanation:

Covalent bond is defined as the bond which is formed when sharing of electrons takes place between the atoms. This is usually formed between two non-metals.

For Example: Formation of hydrogen chloride molecule

Electronic configuration of hydrogen = $1s^1$

Electronic configuration of chlorine = $1s^22s^22p^63s^23p^5$

Hydrogen and chlorine atoms are need only 1 electron to attain stable electronic configuration. So, they share electron and form covalent bond.

Hence, the correct answer is sharing of electrons.

Answer 2

A covalent bond can best be described as a sharing of electrons.

What is a covalent bond?

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. The goal is to obey the octet's rule.
