Question

Name the noble gas which has lowest bioiling point ?

Answer 1

Answer:

Noble gases have very low boiling points because of the corresponding intermolecular forces. The noble gas atoms are inert and non polar, which means very less attractions among them. That means it is easier to convert them from liquid to gas, hence low boiling point

Answer 2

Answer:

*The element with lowest boiling point is helium

*The boiling temperature increases when we move along the group from top to bottom
