Ionic And Metallic Bonding + Atoms

Question 1

Describe the structure of metals

Answer 1

Giant structure
Metal ions in layers
Delocalised electrons

Question 2

Explain why pure metals have high melting and boiling points

Answer 2

Strong metallic bonds between metal ions and delocalised electrons
Require a lot of energy to overcome

Question 3

Describe what happens to electrons in ionic bonding

Answer 3

Transferred from one atom to another

Question 4

If a non metal forms an ion , will it have positive and negative charge

Answer 4

Negative

Question 5

Explain why pure metals are malleable

Answer 5

Layers of metal ions are free to slide over each other

Question 6

Explain why metals are good conductors of thermal energy

Answer 6

Delocalised electrons can move through the metal and transfer energy

Question 7

Describe the structure of a typical alloy

Answer 7

Metallic structure
With atoms of different metals or carbon mixed in

Question 8

Name the 2 different types of substances that form ionic bonds when they react together

Answer 8

Metals and non metals

Question 9

Explain why metals are good conductors of electricity

Answer 9

Delocalised electrons can move through the metal and carry charge

Question 10

If a metal forms an ion, will it have a positive or negative charge?

Answer 10

Positive

Question 11

Ion

Answer 11

An atom with an overall charge
