Which is the heaviest atom?
Give 2 correct reasons why helium balloons float in air.
The mass of a 1 litre helium balloon is the same as the mass of 1 litre of air.
Air is mostly nitrogen. Nitrogen atoms have more protons and neutrons than helium atoms.
If a 1 litre balloon was filled with nitrogen, it would weigh the same as 1 litre of helium.
1 litre of helium has less mass than the same volume of air.
Helium atoms are bigger and so more spread out than nitrogen atoms.
