Group 0: The Noble Gases

Question 1

monatomic definition

Answer 1

a molecule composed of just one atom

Question 2

inert definition

Answer 2

a substance that is not chemically reactive

Question 3

What do the electronic configurations of all the noble gases have in common and what does this mean about their reactivity?

Answer 3

All noble gases have a full outer shell meaning they don’t need to react

Question 4

What are the general physical properties of noble gases?

Answer 4

low density, have a low boiling point, are inert and non-flammable

Question 5

What happens to the size of the atom as you go down group 0?

Answer 5

The atoms get bigger

Question 6

What happens to the boiling points as you go down group 0? Why?

Answer 6

The boiling point increases as you go down group 0. This is because the intermolecular forces become stronger so more energy is required to break these forces

Question 7

What happens to the densities as you go down group 0?

Answer 7

The density increases as you go down group 0
