Question

In a carbon dioxide (CO2) molecule, how many valence electrons does the carbon atom (C) share with each oxygen atom (O)?
How many covalent bonds (single or double) hold the CO2 molecule together?​

Answer 1

Answer:

These are called double bonds. Each O is surrounded by four dots and two sticks or lines, representing another 4 electrons in its double bond. So each O is surrounded by 8 total valence electrons, giving it an octet and making it stable. Carbon has four bonds, in this case present as two double bonds.

There are four covalent bonds in one molecule of carbon dioxide. Carbon dioxide consists of one carbon atom and two oxygen atoms.
