As a domain expert in the field of chemistry, I'm delighted to provide you with a comprehensive overview of gases. Gases are one of the four fundamental states of matter, along with solids, liquids, and plasmas. They are characterized by their ability to expand indefinitely and to fill any container they are placed in. Here are some common examples of gases, along with a brief description of each:
1. Air: A mixture of various gases, primarily composed of nitrogen (about 78%) and oxygen (about 21%), with small amounts of argon, carbon dioxide, and other trace gases.
2. Helium: A noble gas, helium is the second lightest element and is known for its low boiling point and non-reactivity. It's commonly used in balloons and as a cooling medium for certain types of nuclear reactors.
3. Nitrogen: An inert gas that makes up the majority of Earth's atmosphere. It's used in various industrial processes, including the production of fertilizers and as a protective gas during the manufacturing of electronic components.
4. Freon: A brand name for a class of chemicals known as chlorofluorocarbons (CFCs). They were widely used as refrigerants and propellants but are now largely phased out due to their ozone-depleting properties.
5. Carbon Dioxide (CO2): A colorless, odorless gas that is a byproduct of combustion and a critical component of the carbon cycle. It's also used in the production of carbonated beverages and as a greenhouse gas.
6. Water Vapor (H2O): The gaseous form of water, which is essential for life on Earth. It plays a significant role in the Earth's weather and climate systems.
7.
Hydrogen: The lightest and most abundant element in the universe, hydrogen is a highly flammable gas that can be used as a fuel source.
8.
Natural Gas: Primarily composed of methane, it is a fossil fuel used for heating, cooking, and power generation. It's also a significant feedstock for the production of chemicals and fertilizers.
9.
Oxygen: Essential for most life forms, oxygen is a highly reactive gas that supports combustion and is necessary for respiration.
10.
Methane (CH4): The main component of natural gas, methane is also produced by the digestive systems of certain animals and by the decay of organic matter in landfills.

1. Ammonia (NH3): A compound of nitrogen and hydrogen, ammonia is used in the production of fertilizers, as a cleaning agent, and in the chemical industry.

2. Sulfur Dioxide (SO2): A byproduct of the burning of sulfur-containing fuels, sulfur dioxide is used in the production of sulfuric acid and as a preservative.

3. Neon: Another noble gas, neon is used in lighting, particularly in neon signs due to its bright red glow when electrified.
1
4. Xenon: A heavy noble gas, xenon is used in the medical field for imaging and in the automotive industry for high-intensity lamps.
1
5. Radon: A radioactive gas that occurs naturally as a decay product of uranium and thorium. It's a health concern because it can accumulate in buildings and increase the risk of lung cancer.
Understanding the properties and uses of these gases is crucial for various applications, from industrial processes to environmental science and medical applications. Each gas has unique characteristics that make it suitable for specific uses, and their interactions with other substances can lead to a wide range of chemical reactions and phenomena.

Eleven elements-hydrogen, nitrogen, oxygen, fluorine, chlorine, helium, neon, argon, krypton, xenon, and radon-exist as a gas under standard pressure and temperature. Depending on the element, when the temperature or pressure is raised or lowered, then they will shift into another state. ... One example is pure oxygen.
