chlorine, the other three are examples of noble gases
Any noble gas - helium, Neon, Xenon, Argon, Radon
Hydrogen (H2)
Yes, diatomic refers to a molecule comprising of two atoms. Thus nitrogen gas (N2), oxygen gas (O2) and hydrogen gas (H2) are all diatomic. These compounds can also be made up of different elements. Acid-base chemistry aside, hydroflouric acid (HF) and hydrochloride acid (HCl) are also diatomic
Br2 (s) bromine
A monatomic gas has no contribution from vibration to its specific heat. A diatomic gas has both vibration of the two atoms as the stretch and compress the bond between them and can rotate faster or slower. With more ways to store energy than just translational energy, diatomic gases tend to have higher heat capacities.
Chlorine
Nitrogen gas is diatomic.
Oxygen is a diatomic gas.
Yes, nitrogen is diatomic.
The molecule of nitrogen contain two atoms, is diatomic.
A diatomic gas
Nitrogen monoxide is a diatomic gas at standard temperature and pressure.
This gas is nitrogen.
A molecule; for a diatomic gas this would be something like H2 , Cl2 etc. A compound would be CO2 or CH4 for example.
Yes, hydrogen gas exists as a diatomic molecule with the formula H2.
A diatomic gas
