How many bonding and nonbonding electrons are on the carbon atom in co2?
a) 2, 6
b) 4, 4
c) 6, 2
d) 8, 0

There are 8 bonding electrons and 0 nonbonding electron on carbon atom

Explanation:

consists of two C=O bonds.

Total number of valence electrons in are 16.

Two C=O bonds uses 8 electrons from 16 available electrons. Rest of the electrons are used to fulfill octet of two oxygen atoms.

Hence 8 electrons are present as nonbonding electrons on two oxygen atoms.

So, Carbon atom contains 8 bonding electrons and 0 nonbonding electrons.
