The simplest hydrocarbon , methane is a gas with a chemical formula of CH4. The carbon atom central to the methane molecule has 4 valence electrons and thus needs 4 more electrons from four hydrogen atoms to complete its octet. The hydrogen atoms have a 109 degree bond angle giving the molecule a tetrahedral geometry . A principal component of natural gas, methane is significant .
Methane, CH4, is a chemical compound composed of one carbon atom and four hydrogen atoms. It is one of the most common gases in the universe, as well as on Earth.While it is valued for its energy-production capabilities, methane also has the ability to potentially wreak havoc on the Earth's fragile ecosystems.n addition to natural gas-fired electrical generation stations, there are other uses for methane as an energy source as well. It is currently being used to power some automobiles and NASA is considering its use as a fuel for space vehicles.
