3.5.1 - Metal Structure, Bonding And Properties

Question 1

What are the two components of the STRUCTURE of a METAL !?

Answer 1

. A LATTICE of POSITIVE METAL IONS

. A “SEA” of DELOCALISED ELECTRONS

Question 2

Definition of METALLIC BONDING:

Answer 2

. Metallic bonding is the ELECTROSTATIC ATTRACTION between the POSITIVE METAL IONS and the NEGATIVE DELOCALISED ELECTRONS

Question 3

Is METALLIC bonding a weak or strong attraction !?

Answer 3

. Metallic bonding is usually a VERY STRONG ATTRACTION

Question 4

Do METALS have HIGH or LOW melting points !?

Answer 4

. Metals tend to have HIGH melting points

• because metallic bonding is VERY strong so LOTS of energy is needed to break it

Question 5

Do METALS conduct electricity⚡️ !?

Answer 5

. Yes metals do conduct electricity, this is because the DELOCALISED ELECTRONS are FREE TO KOVE through the lattice

Question 6

Are METALS malleable !?

Answer 6

. Metals are malleable, this is because the LAYERS OF METAL IONS can SLIDE over each other
