Study Notes
Ions
- Electrons are negatively charged particles that orbit the nucleus of an atom.
- Losing or gaining electrons transforms atoms into ions.
Ionic Bonds
- Ionic bonds form between oppositely charged ions.
- Sodium (Na) atoms lose an electron, becoming positively charged sodium ions (Na⁺).
- Chlorine (Cl) atoms gain an electron, becoming negatively charged chloride ions (Cl⁻).
- The attraction between these oppositely charged ions forms an ionic bond.
- The resulting compound is sodium chloride (NaCl), known as table salt.
