Chapter 3 - Metallic Bonding

Question 1

What is metallic bonding?

Answer 1

metal + metal

Question 2

How does metallic bonding work?

Answer 2

metal atoms lose outer shell of electrons to form positive ions. Delocalised electrons surround positive ions and hold them together

Question 3

Properties of metals?

Answer 3

1. high melting point
2. conduct electricity
3. conduct heat

Question 4

What is an alloy?

Answer 4

A mixture of two or more metals with different properties

Question 5

Metallic bonding…

Answer 5

sheds electrons

Question 6

Properties of metallic bonding:

Answer 6

1. cat ions
2. conducts electricity
3. shedding electrons
4. high melting and boiling point
5. charges go wherever they want = flow of electrons so cat ions can move
