Group 0 elements Flashcards
1
Q
What is group 0 called ?
A
Noble gases, they include helium, neon, argon, they are all colourless gases
2
Q
How many electrons do they have on there outer shells ?
A
8 apart from helium which has two- they are stable
3
Q
What does the stability do ?
A
Makes them unreactive which means they do not form molecules easily, so they are single elements
4
Q
What happens because of the noble gases being very unreactive ?
A
Some reactions are carried out within the atmosphere
5
Q
What happens as you go down the noble gases ?
A
Relative atomic masses decrease- when you go down the group more elements have more electrons
6
Q
What does having more electrons mean ?
A
Stronger forces between atoms, they have a higher boiling point
7
Q
What are the noble gases ?
A
helium, argon, krypton, xenon , radon
