1. Oxygen: Oxygen is a chemical element with the symbol O and atomic number 8. It is a colorless, odorless, and tasteless gas. It is the second most abundant element in the Earth's atmosphere and is essential for the survival of most organisms. Oxygen plays a crucial role in combustion, respiration, and the formation of various compounds.
2. Carbon Dioxide: Carbon dioxide is a chemical compound consisting of one carbon atom bonded with two oxygen atoms, with the chemical formula CO2. It is a colorless gas at standard temperature and pressure and is a greenhouse gas. Carbon dioxide is produced by various natural and human activities, including respiration, combustion of fossil fuels, and deforestation.
3. Ozone: Ozone is a molecule composed of three oxygen atoms, with the chemical formula O3. It is a pale blue gas with a distinct odor. Ozone is present in the Earth's atmosphere and is beneficial when located in the stratosphere, where it forms the ozone layer. This layer protects the Earth from harmful ultraviolet radiations. However, near the surface, ozone is a pollutant and can be harmful to human health.
4. Nitrogen: Nitrogen is a chemical element with the symbol N and atomic number 7. It is a colorless, odorless, and tasteless gas and makes up about 78% of the Earth's atmosphere. Nitrogen is an essential component of proteins and nucleic acids and is crucial for the growth and development of living organisms. It is also used in various industrial processes like manufacturing fertilizers and explosives.
5. Hydrogen: Hydrogen is a chemical element with the symbol H and atomic number 1. It is the lightest and most abundant element in the universe, making up about 75% of its elemental mass. Hydrogen exists as a diatomic gas (H2) and has numerous applications, such as being used as a fuel source, in the production of ammonia, in the petroleum industry, and in the synthesis of various chemicals.
