Identify the molecular formula given: C\_2H\_4, which corresponds to ethene.
Recall that ethene is an alkene, characterized by a carbon-carbon double bond.
Determine the bonding for each carbon atom: since each carbon forms a double bond with the other carbon, it can form two additional single bonds to satisfy the tetravalency (four bonds total) of carbon.
Assign the remaining bonds to hydrogen atoms: each carbon will be single-bonded to two hydrogen atoms to complete its four bonds.
Conclude that the Lewis structure of ethene consists of each carbon atom double-bonded to the other carbon and single-bonded to two hydrogen atoms.
