Methane molecules,computer artwork. Four different molecular models of a methane molecule (CH4). One carbon atom is surrounded by four hydrogen atoms in tetrahedral symmetry. Each molecule is surrounded by van der Waals radii (yellow). Methane,part of the alkanes,is a colourless,odourless gas. It is the chief constituent of natural gas,which is used as a fuel. It can be formed by the decay of vegetable matter. When released into the atmosphere,methane helps to trap the heat of the Sun,acting as a greenhouse gas and contributing to global warming | |
