Forms when atoms gain or lose electrons are called?

• A. Hydrogen bond
• B. Covalent bond
• C. Ionic bond
• D. Metallic bond

Answer: (C)

The key idea is that transferring electrons creates ions, and the electrical attraction between those oppositely charged ions forms the bond. When atoms lose electrons (becoming positive) or gain electrons (becoming negative), they become charged particles that stick together through this strong electrostatic attraction. That’s what an ionic bond is. It’s different from covalent bonds, where atoms share electrons; from hydrogen bonds, which are weak attractions involving hydrogen between molecules; and from metallic bonds, where a "sea" of delocalized electrons surrounds metal ions. So the term that describes bonds formed by transferring electrons is the ionic bond.
