Metallic Bonding

Question 1

Metallic bonding involves what?

Answer 1

Delocalised electrons

Question 2

The electrons in the outer shell of a metal atom are what

Answer 2

Delocalised

Question 3

What holds the atoms together in metallic bonding?

Answer 3

The forces of electrostatic attraction between the positive metal ions and the shared negative electrons

Question 4

What substances are held together by metallic bonding?

Answer 4

Metallic elements and alloys

Question 5

What state of matter are most metals at room temperature?

Answer 5

Solid

Question 6

Why are metals good conductors of electricity and heat?

Answer 6

Because they have delocalised electrons

Question 7

Alloys or pure metals harder?

Answer 7

Alloys

Question 8

Why is an alloy harder than a pure metal?

Answer 8

Pure metal is often too soft mixing them with other elements makes them harder. Different elements have different sized atoms so when another element is mixed with a pure metal the new metal atoms will distort the layers of metal atoms making it more difficult for them to slide over each other.

Question 9

What are alloys?

Answer 9

Alloys are 2 or more elements in a substance
