Group 0 elements

Question 1

Why are group 0 elements unrecative?

Answer 1

• Because they have a full outer shell of electrons.

Question 2

How does the boiling/ melting point change as you go down the group?

Answer 2

• Boiling/ melting point increases.
• RAM increases= size of atoms increase
• Greater van der waals….

Question 3

What do noble gases exist as?

Answer 3

• Exist as single atoms.

Question 4

Q: The boiling point of Xenon is -108. Predict with reasoning whether Kr will be a s/l/g at this temperature.

Answer 4

• Kr has lower boiling point that Xe
• So it will be a gas at this temperature

Question 5

Do Group 0 elements form molecules of themselves easily?

Answer 5

• No.
• They are unreactive

Question 6

Which noble gas is the only one that doesn’t have 8 electrons on outer shell?
How many does it have?
