- Ionic Compounds
- Ionic bonding - the metal is oxidised and the non-metal is reduced.
- The no. of ions formed by a non-metal is equal to the group no. - 8
- No. of ions on a metal = group number
- Ionic Compounds
- When metals react with non metals, the non metal atoms become negatively charged and the metal becomes positively charged
- Ions in a Ionic Compound are arranged in a lattice structure.
- There are strnong electrostatic charges between atoms in ionic compounds which mean that lots of energy is needed to split apart positive and negative ions.
- They have high melting and boiling points
- Solid Ionic compounds don't conduct heat because ions are held in place. Ions cannot move to conduct the current.
- The greater the charge on an ion, the stronger the forces are holding them together.
- Ionic bonding - the metal is oxidised and the non-metal is reduced.
