Natural gas primarily consists of:

Natural gas is primarily composed of methane, which is a simple hydrocarbon molecule consisting of one carbon atom and four hydrogen atoms (CH₄). Methane is the most abundant component of natural gas, typically making up about 70-90% of its composition. This high concentration makes it the principal fuel source in various applications, including heating, electricity generation, and as a raw material in the chemical industry.

In addition to methane, natural gas may contain small amounts of other hydrocarbons, such as ethane, propane, and butane, but these components are minor compared to methane's predominance. Understanding the composition of natural gas is essential for recognizing its role as a clean-burning fuel and for its usage in various applications.
