ionic bonding

Ionic bond occurs between..

Metal and non-metal

Electrons are transferred from where?

Metal to non-metal

What is formed

Positive and negative ions are formed

Why bonds form

To achieve a stale e- arrangement

When a metal loses a e- It is…

Oxidisation

When non-metal gains an e- it is…

Reduced

Ionic bonding is the result of

Electrostatic attraction between oppositely charged ions

Ionic compounds always exist in what structure

Lattice

3 things that determine the strength of the bond

Charge of ions- bigger charge there is more attraction

Radius if ions- bigger ions, weaker bonds

Geometry- shape

5 Properties of ionic compounds

1. Solid at room temperature

2. High m.p/b.p (giant lattice)

3. Doesn’t conduct when solid

4. Does conduct when molten or aqueous

5. Brittle
