Group 0 - Periodic Table

Question 1

What are all the group 0 gases? What do they all have in common?

Answer 1

Unreactive, colorless gases at room temp
All have 8 outer shell electrons besides helium which has 2
Makes them very unreactive due to stability

Question 2

What is the name of the group 0 group of elements?

Answer 2

Noble gases

Question 3

What are the patterns in properties of the noble gases?

Answer 3

Relative atomic masses increase as you go down the group
This means as you go down, they get more electrons
More electrons means stronger forces between atoms
Stronger the forces, higher the boiling point, so as you go down group 0, boiling point also increases.
