Metallic bonding

Question 1

What do you call free moving electrons?

Answer 1

delocalised

Question 2

Properties of metallic compounds

Answer 2

1. Good conductor of electricity (electrons)
2. Good conductors of heat (HE transferred through moving electrons)
3. High b.p/ m.p (held tgt by strong metallic bonds, require large amounts of HE to…)
4. Malleable (diff shapes) and ductile (not brittle) held tgt by strong metallic bonds, pressure can cause latters of ions to slide over another
