Mercury is the only substance listed that is not a gas at room temperature. Nitrogen, oxygen, and helium are all gases in their normal state.
At room temperature: Oxygen & Nitrogen are gases, Carbon is solid, & Mercury is a liquid.
Oxygen and nitrogen are gases at room temperature, while carbon and mercury are not.
Neon: Ne Helium: He Nitrogen: N Oxygen: O Carbon: C
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.

Helium is not found in caffeine. Caffeine is made up of carbon, hydrogen, nitrogen, and oxygen atoms. Helium is a noble gas and is typically not found in organic compounds like caffeine.
Examples of gases: oxygen, helium, radon, nitrogen, etc.
The most common gas in the atmosphere of Mercury is oxygen, followed by helium, sodium, hydrogen, and potassium. However, the overall atmosphere of Mercury is very thin and composed mainly of oxygen.
