What is the Structure of a Methane Molecule?
A carbon atom has 4
electrons in its
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.
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
represent single covalent bonds.
