Question

which element(gas at room temperature) has highest condensation point ?

Answer 1

1. Xenon is the noble gas that is gaseous at room temperature and posses highest condensation point.

2. By condensation point we mean that the temperature at which gas changes to liquid.

3. Xenon atoms being highly stable, and having high electron density, are not stable being in vicinity, so it requires high temperature to bring them closer and turn it into liquid.
