Here are 15 types of gases:
- Oxygen (O₂) – Essential for respiration and combustion.
- Nitrogen (N₂) – Makes up about 78% of Earth’s atmosphere.
- Carbon Dioxide (CO₂) – Produced by respiration and combustion, used in photosynthesis.
- Hydrogen (H₂) – The lightest and most abundant element in the universe.
- Helium (He) – An inert noble gas, used in balloons and cryogenics.
- Argon (Ar) – A noble gas used in welding and lighting.
- Methane (CH₄) – A greenhouse gas and a primary component of natural gas.
- Neon (Ne) – Used in neon signs and lighting.
- Ammonia (NH₃) – Used in fertilizers and refrigeration.
- Chlorine (Cl₂) – A toxic gas used in water purification and chemical production.
- Ozone (O₃) – Found in the ozone layer, protects Earth from UV radiation.
- Radon (Rn) – A radioactive noble gas found in soil and rocks.
- Sulfur Dioxide (SO₂) – Produced by volcanic eruptions and burning fossil fuels.
- Nitrous Oxide (N₂O) – A greenhouse gas, also known as laughing gas.
- Carbon Monoxide (CO) – A toxic gas produced by incomplete combustion.
