Neutral gases refer to gases that are not electrically charged. They are made up of atoms or molecules that have an equal number of protons and electrons, resulting in a neutral overall charge. Neutral gases do not have any net electrical charge and do not exhibit ionization or the formation of ions.

Some examples of neutral gases include:

- Helium (He)

- Neon (Ne)

- Argon (Ar)

- Krypton (Kr)

- Xenon (Xe)

- Radon (Rn)

These noble gases are considered neutral gases and are located in Group 18 (or VIIIA) of the periodic table. They have complete and stable outer electron shells, making them highly unreactive and chemically inert under ordinary conditions.

Neutral gases are commonly used in various applications such as lighting, gas-filled balloons, refrigeration, scuba diving, and medical imaging due to their inert and stable nature. They can provide an inert environment or atmosphere in industrial processes and scientific experiments, and are also used in specialized lighting applications where colored lighting effects are desired.
