Monatomic gases: Monatomic gases consist of individual atoms that are not chemically bonded, such as helium (He) and neon (Ne).
Polyatomic gases: Polyatomic gases are molecules composed of more than two atoms. An example is carbon dioxide (CO2).
Ideal gas law: The ideal gas law describes the behavior of an ideal gas and relates pressure, volume, temperature, and the number of moles present.
