      Oh yes! Different gases are made up of different molecules or elements, and each of them has a different number of protons, neutrons and electrons. So different gases will have different weights.

      And yep – air does weigh! In fact, the air pressing down on your head right now weighs about 1 tonne. Yes, 1 tonne!
