1 h Metallic bonding

Question 1

What happens to the valence electrons within the metal lattice

Answer 1

Metal becomes positively charged

Question 2

How do delocalised electrons move

Answer 2

Between positive metal ions like a sea of electrons

Question 3

Why are metallic bonds strong

Answer 3

Attraction between positive metal ions and delocalised electrons (-)

Question 4

Why do metals have high melting points

Answer 4

-Many strong metallic bonds in giant metallic structures
-A lot of energy needed to break these bonds and overcome forces

Question 5

Why do metals conduct electricity

Answer 5

-Have free electrons that move and carry charge
-Electrons entering one side and cause displacement of electrons on the other
-Hence electricity can be conducted

Question 6

What does malleable mean

Answer 6

Ability to change shape without breaking or cracking

Question 7

What does ductile mean

Answer 7

Ability to deform and stay in the shape

Question 8

How are metals malleable and ductile

Answer 8

-Layers of positive ions can slide over on another to take up different positions
-Valence electrons move with them as they dont belong to any particular metal atom
