a representation of the molecule $co_2h$ is shown below. does this image show an accurate and complete representation of bonds within a molecule? no, the carbon atom has too many valence electrons. yes, the hydrogen atom is an exception to the octet rule. no, one of the oxygen atoms has too many valence electrons. no, one of the oxygen atoms doesnt have enough valence electrons. yes, all of the atoms are following the octet rule.

Answer

Brief Explanations:

The octet rule states that atoms tend to have 8 valence - electrons in their outer shell for stability, except for hydrogen which only needs 2. In the given $CO_2H$ molecule, carbon has 4 valence - electron bonds, each oxygen has 8 valence electrons (including lone pairs and bonding electrons), and hydrogen has 2 valence electrons. Hydrogen is an exception to the octet rule as it only requires 2 electrons to fill its 1s orbital.

Answer:

Yes, the hydrogen atom is an exception to the octet rule.
