CH4 (Methane)

Methane (CH₄) is a colorless, odorless gas that is the simplest form of hydrocarbon, consisting of one carbon atom bonded to four hydrogen atoms. It naturally forms in environments like wetlands, rice paddies, and the digestive systems of some animals, such as cows. Methane is also produced during the decay of organic waste in landfills and during the extraction of fossil fuels like natural gas. It is a potent greenhouse gas—more effective at trapping heat in our atmosphere than carbon dioxide—contributing to climate change. Methane plays a significant role in both natural processes and energy production.
