1.52-1.53 metallic bonding

Question 1

describe a metallic lattice

Answer 1

Metals have a giant regular arrangement of layers of positive ions surrounded by a sea of delocalised electrons.

Question 2

describe metallic bonding in terms of electrostatic attractions

Answer 2

Metallic bonding is the strong electrostatic attraction between positive metal ions and a sea of delocalised electrons

Question 3

explain typical physical properties of metals

Answer 3

-Metals are good conductors because they have delocalised electrons which are free to move.

-Metals are malleable (can be hammered into shape) because they have layers of ions that can slide over each other.
