6.a.Properties of bonding

Question 1

What are the 4 types of bonding?

Answer 1

Ionic Metallic Covalent molecular Covalent network

Question 2

Which type of bonding is never found in elements?

Answer 2

Ionic

Question 3

In which states do ionic compounds conduct electricity?

Answer 3

Molten and in solution

Question 4

Why don’t ionic compounds conduct in solid state?

Answer 4

The ions are not free to move?

Question 5

Why can’t the ions move in an ionic lattice?

Answer 5

They are held together by electrostatic attractions

Question 6

In which states do metals conduct electricity?

Answer 6

Solid and molten

Question 7

In which states do covalent substances conduct electricity?

Answer 7

The DO NOT conduct electricity

Question 8

Which has the higher melting and boiling points. Covalent networks or covalent molecular?

Answer 8

Covalent networks

Question 9

Why do covalent networks have high melting and boiling points?

Answer 9

You have to break a lot of covalent bonds which takes a lot of energy
