What is the Structure of a Methane Molecule?

A carbon atom has 4 electrons in its outer shell.
Carbon is in group 4 of the periodic table.
A hydrogen atom has 1 electron in its outer shell.
Hydrogen can only form 1 bond.

Four hydrogen atoms will each share their
1 electron with carbon to form four covalent bonds
and make a methane molecule  (CH₄).

The pairs of shared electrons between each
hydrogen atom and carbon
show single covalent bonds - see covalent bonding.

Methane is commonly represented by the structural formula

where the single lines between the atoms
represent single covalent bonds.
