Helium has smaller particles than nitrogen or oxygen. Helium atoms are smaller in size, as they have fewer protons and neutrons in their nucleus compared to nitrogen or oxygen atoms. This smaller size allows helium atoms to move more freely and escape into the atmosphere, which is why helium is a lighter gas.
The most abundant gas on Mercury is oxygen. However, it exists primarily in the form of compounds like silicates and oxides rather than as a free gas. Mercury's thin atmosphere also contains trace amounts of helium, sodium, hydrogen, and potassium.

Stars are primarily made of hydrogen and helium, with trace amounts of other elements like carbon, oxygen, and iron. These elements are formed through nuclear fusion in the cores of stars.
