What is the difference between ionic and covalent bonds?

Chemistry

ScanSolve AI Answer

Ionic bonds form when one atom transfers electrons to another, creating oppositely charged ions that attract each other. • Typically between metals and nonmetals • Example: NaCl (Na⁺ and Cl⁻) • Usually form crystalline solids, conduct electricity when dissolved

Covalent bonds form when atoms share electrons. • Typically between two nonmetals • Example: H₂O (hydrogen shares electrons with oxygen) • Can be polar (unequal sharing) or nonpolar (equal sharing)

Quick rule: Large electronegativity difference → ionic. Small difference → covalent.
