Metals and Metallic bonding

Question 1

why are most metals malleable?

Answer 1

Metal atoms are arranged in a neat layer and are surrounded by delocalised electrons which allow them to slide

Question 2

Explain why Barium has a high melting point.

Answer 2

• has a lattice structure of positive ions in a sea of delocalised electrons
• has a stronger force of attraction
• therefore, a lot of heat energy needed to melt it

Question 3

what is metallic bonding between?

Answer 3

metal and a metal
