Science 7/Periodic Table - Noble Gases, Group 8 Elements Flashcards
1
Q
What group do the Noble Gases belong to?
A
Group 8/ Group 0
2
Q
What elements occupy group 8?
A
Noble Gases
3
Q
List all the elements for group 8?
A
Helium Neon Argon Krypton Radon
4
Q
Which element is the most reactive in group 8?
A
Radon as it is very radioactive
But some say xenon because it has been experimented on more due to it not being radioactive
5
Q
Are noble gases generally reactive or non reactive and why
A
- Non-reactive
- Outer most shell is completely filled with atoms so they do not need to share off any other elements; when sharing/merging it creates a reaction
6
Q
Uses of Noble Gases
List at least one bullet point for each element
A
Helium = Glowing lights, party/scientific balloons, inflate blimps Neon = Neon sign Argon = Wielding Krypton = Energy saving, neon light Xenon = Photographic flashes Radon = Cancer therapy as it emits radiation
7
Q
