carbon dioxide molecule ( CO2 ) , a single carbon atom is joined to two atoms of
oxygen by double covalent bonds . The structural formula for CO2 is shown here :
O = C = 0 Each line in a structural formula represents a pair of shared electrons ...

O H H N NIH H Urea Again , each atom has the required number of covalent
bonds . In this case , one carbon atom is involved in both single and double
bonds . Both urea and carbon dioxide are molecules with only one carbon atom .
