Q: Are Group 0 elements reactive?

A: No, Group 0 elements are unreactive

Q: What is the reason for the low reactivity of noble gases?

A: The low reactivity of noble gases is due to their full outer shells so do not need to react to gain or lose electrons

Q: What are some common uses of He?

A: Helium balloon

Q: Why are noble gases used in lighting?

Q: What is the noble gas used in street signs?

A: Neon

Q: How does the boiling point of noble gases change as you move down Group 0?

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