how does the Outer shell of Group 8 elements look

The outer shell of Group 8 elements is full, with 8 electrons except for helium, which has 2.

3
New cards

what is the Reactivity of Group 0 elements

Group 0 elements are unreactive.

4
New cards

why do they have Low reactivity

The low reactivity of noble gases is due to their full outer shells, so they do not need to gain or lose electrons.

5
New cards

Common use of He

Helium is commonly used in helium balloons.

6
New cards

what Noble gases is used in lighting and why

Argon is used in lighting as it does not react with the metal filament.

7
New cards

how do noble gases look naturally

Noble gases exist as individual atoms in nature and do not form compounds with other elements.

8
New cards

Boiling point of noble gases

Noble gases have low boiling points and are gases at room temperature.

9
New cards

Density of noble gases

Noble gases have low densities.

10
New cards

what is the Noble gas used in street signs

Neon is used in street signs.

11
New cards

how the Boiling point of noble gases in Group 0 change as you go down the group

The boiling points of noble gases increase as you move down the group, indicating an increase in the strength of intermolecular forces.

12
New cards

why is He used for helium balloons (give 2 reasons)

Helium is suitable for use in helium balloons because it is unreactive and less dense than air.
