Topic Summary: Ionic Bonding
Key Terms
- Ionic bond: electrostatic attraction between oppositely charged ions
- Cation (+): metal loses electrons
- Anion (-): non-metal gains electrons
- Electron transfer: electrons move from metal to non-metal
- Electrostatic attraction: force between opposite charges
Must-Know Facts
- Ionic bonding occurs between metals and non-metals
- Metals LOSE electrons → positive ions (cations)
- Non-metals GAIN electrons → negative ions (anions)
- Both ions achieve noble gas electron configuration
- Group 1 → +1, Group 2 → +2, Group 6 → -2, Group 7 → -1
