Chemical bond formed when electrons are gained or lost
A
covalent
B
ionic
C
hydrogen
D
peptide
Explanation: 

Detailed explanation-1: -An ionic bond can be formed after two or more atoms loss or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons. Ions with opposite charges will attract one another creating an ionic bond.

Detailed explanation-2: -An ionic bond is a bond that forms when electrons are transferred from one atom to another atom. B. Charged Particles Ions are charged particles that form when atoms gain or lose electrons.

Detailed explanation-3: -The Octet Rule requires all atoms in a molecule to have 8 valence electrons–either by sharing, losing or gaining electrons–to become stable. For Covalent bonds, atoms tend to share their electrons with each other to satisfy the Octet Rule.
