Its work ability should be what you need<span />
It is so because warm air is lighter than cold air. Cold air means the molecules are not moving as much, so they will feel like sticking together and will not jump around as molecules in warm air will(higher temp. means higher KE). Think of a solid, colder solids are much heavier than warmer ones(think of ice-starts melting).

You can simply subtract the atomic number from the mass number in order to find the number of neutrons.
