Ionic Bonding (See your own notes for diagrams!)
- Ionic compounds are formed when metals react with non-metals.
- Ionic bonding is when atoms transfer electrons, atoms either lose or gain electrons.
- Ions formed are held to each other by enormously strong forces of attraction between oppositely charged ions.
- This electrostatic force of attraction is called the ionic bond.
- Ionic bonds always produce giant ionic structures.
- They are in a regular lattics arrangement.
- There are very strong chemical bonds between all of the ions.
- A single crystal of salt is 1 giant ionic lattice.
- Because of the very strong chemical bonds, they have very high melting and boiling points.
- When dissolved the ions seperate and are free to move in the solution and so they carry an electric current.
- When they melt, ions are free to move and carry electric current.
