Group 0 elements Flashcards
1
Q
Why are group 0 elements unrecative?
A
- Because they have a full outer shell of electrons.
2
Q
How does the boiling/ melting point change as you go down the group?
A
- Boiling/ melting point increases.
- RAM increases= size of atoms increase
- Greater van der waals….
3
Q
What do noble gases exist as?
A
- Exist as single atoms.
4
Q
Q: The boiling point of Xenon is -108. Predict with reasoning whether Kr will be a s/l/g at this temperature.
A
- Kr has lower boiling point that Xe
- So it will be a gas at this temperature
5
Q
Do Group 0 elements form molecules of themselves easily?
A
- No.
- They are unreactive
6
Q
Which noble gas is the only one that doesn’t have 8 electrons on outer shell?
How many does it have?
A
- Helium
- Has 2
