An ionic bond is the bonding (agg) between a non-metal and a metal, that occurs when charged atoms (ions) attracted. This happens after a metal atom loses one or more of its electrons to the non-metal atom. This makes the bond stronger and harder to break. A maximum of 3 electrons can be transferred in the process.
Features of ionic bonds[change | change source]
- Three dimensional structures called an ionic lattice.
- Soluble in water.
- In a solid state they do not conduct electricity. However, in a liquid state or when dissolved in water, they will conduct electricity well because the ions are free to move.
- They contrast to the characteristics of a covalent bonds.
- Sometimes if they do not have a spare valence electron to create a complete shell one will act as two and spin in a figure of eight around both atoms.
- Ionic bonds are a lot weaker than covalent bonds.
- High melting/boiling point.
