Answer 1

1 = 2
2 = 8
3= 18
4= 32

Question 2

What shape is an S orbital

Answer 2

sphere

Question 3

What shape is an P orbital

Answer 3

dumbbell

Question 4

Explain the melting point of ionic bonding

Answer 4

Very high because a large amount of energy would be needed to overcome the strong electrostatic attractions

Question 5

Explain the strength of ionic compounds

Answer 5

Very brittle

Question 6

Do ionic compounds conduct electricity?

Answer 6

Not when solid because they are in a lattice but do when molten.

Question 7

What is ionic bonding

Answer 7

Electrostatic force of attraction between oppositely charged ions

Question 8

What is covalent bonding

Answer 8

Strong electrostatic attraction between a shared lair of electrons

Question 9

Do covalent molecules conduct electricity

Answer 9

No
