Question

What best describes the bonding in a carbon dioxide molecule?

Answer 1

Answer:

B. Carbon shares 2 pair of electrons with each oxygen.

Explanation:

• Carbon dioxide is formed from combustion reactions, which involves a reaction between carbon and oxygen gas.

• Carbon dioxide molecule is formed from one carbon atom and two oxygens. As an element, carbon only has 4 outer shell electrons and oxygen 6.

• The two atoms require to gain electrons to achieve a stable configuration; carbon require to gain four electrons and oxygen requires two electrons.

• Double covalent bonds form between the atoms, where two electrons from each atom are shared making 4 bonding electrons in total.
