Question

Determine the number of bonding electrons and the number of nonbonding electrons in the structure of co2. enter the number of bonding electrons followed by the number of nonbonding electrons in the dot structure of this molecule separated by a comma (e.g., 1,2).

Answer 1

There are double bonds between the C and each O.Since O belongs to VI A group so its valance is 6 after bonding ( double bond) each O has 2 lone pairs → 4 non-bonding e-'s on each O atom resulting 4 + 4 = 8 non- bonging e-'sNo . of bonding e-'s are also 8 since 4 e-'s are involved ineach C = O bond.So answer format is 8 , 8

Answer 2

There are eight bonding electrons and eight non bonding electrons in CO2 molecule.

The molecule CO2 has a total of 16 valence electrons. There are two pi bonds and two sigma bonds in the molecule. Now recall that each bond must consist of two electrons that are shared.

In the view of the statements above and considering the Lewis structure shown, there are eight bonding electrons and eight non bonding electrons in CO2 molecule.
