Question

explain chemical properties of group 18 element​

Answer 1

Answer:

They are all noble gases

Explanation:

*The atomic size of noble gases increase when going down the group

*They have very low melting and boiling points which is why they will always be gas form in room temperature

* their melting and boiling points temperatures increase as you go down the group

*They have a low density

*

Answer 2

Answer:

The Group 18 elements are also known as Zero Group and Noble gases also.

The chemical properties of them are :-

• they are colourless, odourless, non flammable, monotonic gases that have low chemical reactivity.
• the full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons.
