Question

why the values of boiling points of noble gases increase from top to bottom within a group

Answer 1

Hello your answer...

The values of the boiling point increases because The van der waals force increases since the atoms have more electrons as you decent the groups volatility decreases down the group as the boiling point increase as you go down the 7halogens it becomes less reactive .

Or

the value of boiling point increases because of the increase of density down the group is correlated with the increase in atomic mass all the noble gas has a interamatic force and theirfore very low boiling and melting points compared elements of other group...


thanks
