An oxygen atom has 6
electrons in its
outer
shell.
Oxygen is in group 6 of the periodic table.
A carbon atom has 4 electrons in its
outer shell.
Carbon is in group 4 of the periodic
table.
Two oxygen atoms and 1 carbon
atom will each share
two electrons
to form
four covalent bonds and make a carbon dioxide molecule (CO2).
Carbon
dioxide has a double bond on
each side of the carbon atom.
Each electron pair is one bond.
The structural formula of a carbon dioxide molecule is
