Question

carbon atoms have four valence electrons. oxygen atoms have six valence electrons. carbon and oxygen can share electrons so that each atom obtains a full outer shell of 8 valence electrons. draw the shared electrons on this diagram. introduction and instructions carbon (c) oxygen (o)

Explanation:

Step1: Analyze carbon's need

Carbon has 4 valence - electrons and needs 4 more to have a full outer - shell of 8.

Step2: Analyze oxygen's need

Oxygen has 6 valence - electrons and needs 2 more to have a full outer - shell of 8.

Step3: Determine electron - sharing

Carbon and oxygen can form a double bond. Carbon shares 2 of its electrons with oxygen, and oxygen shares 2 of its electrons with carbon. So, on the diagram, draw two pairs of shared electrons (represented as lines or dots) between the carbon and oxygen atoms.

Answer:

Draw two pairs of shared electrons (either as lines or dots) between the carbon and oxygen atoms on the given diagram to represent the double - bond where they share electrons to achieve a full outer shell of 8 valence electrons each.
