- IONIC BONDING
- Occurs between non-metals and metals
- Eg. sodium and chlorine.
- Sodium is a metal - has one outer electron.
- Loses one electron.
- Stable electronic configuration - noble gas electron structure.
- Gains one electron.
- Negatively charged ion - 1-
- Gains one electron.
- Stable electronic configuration - noble gas electron structure.
- Loses one electron.
- Chlorine is a non-metal - it has 7 outer electrons.
- Gains one electron.
- Negatively charged ion - 1-
- Gains one electron.
- Sodium is a metal - has one outer electron.
- PROPERTIES
- Solid at room temperature
- High melting and boiling points.
- Brittle - shatter easily
- If sharp force applied down line of ions, may move ions & produce contact with ions of same charges (since is a lattice of alternating charge).
- Repel
- If sharp force applied down line of ions, may move ions & produce contact with ions of same charges (since is a lattice of alternating charge).
- Conduct electricity when molten or dissolved.
- Ions free to move and therefore carry current from cathode to anode.
- Solid at room temperature
