Flashcards
0/20
Oxygen (O2)
Essential for respiration in aerobic organisms and involved in combustion processes.
Argon (Ar)
Acts as a non-reactive filler gas in the atmosphere.
Ozone (O3)
Absorbs harmful ultraviolet radiation in the stratosphere.
Methane (CH4)
Strong greenhouse gas that contributes to the Earth's warming.
Nitrogen (N2)
Main component of the atmosphere, responsible for inert environment and crucial for the nitrogen cycle.
Carbon Dioxide (CO2)
Contributes to the greenhouse effect and is a key reactant in photosynthesis.
Nitrous Oxide (N2O)
Greenhouse gas with significant global warming potential and involved in atmospheric chemical reactions.
Water Vapor (H2O)
Reinforces the greenhouse effect and is essential for cloud formation.
Helium (He)
Inert gas used in balloons and as a shield gas in certain industrial processes.
Neon (Ne)
Inert gas used in neon signs and high-voltage indicators.
Hydrogen (H2)
Lightest and most abundant element in the universe, has potential as a clean fuel.
Ammonia (NH3)
Plays a role in the nitrogen cycle and is used in agriculture as fertilizer.
Xenon (Xe)
Inert gas used in light sources and medical imaging.
Sulfur Dioxide (SO2)
Produces acid rain and has implications for human health and the environment.
Freons (CFCs)
Synthetic compounds causing ozone layer depletion.
Radon (Rn)
Radioactive gas that can cause lung cancer upon exposure.
Krypton (Kr)
Inert gas used in lighting and insulation applications.
Chlorine (Cl2)
Used in the disinfection of water but harmful to the ozone layer as a reactive gas.
Hydrogen Sulfide (H2S)
Toxic and flammable gas with a characteristic smell of rotten eggs.
Carbon Monoxide (CO)
Toxic gas resulting from incomplete combustion, can be fatal when inhaled in large quantities.
