An ionic bond is the bonding between a non-metal and a metal, that occurs when charged atoms (ions) attract. This happens after a metal atom loses one or more of its electrons to the nonmetal atom. This makes the bond stronger and harder to break.
Features of ionic bonds[change | change source]
- Three dimensional structure called an ionic lattice.
- Soluble in water.
- They are compounds formed from metals and non-metals.
- 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 bond.
- 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.
