An atom of carbon (c) forms covalent bonds with two atoms of oxygen (o) to form carbon dioxide. how are the valence electrons of these atoms rearranged to form the bonds?
a. electrons are transferred from the carbon atom to the oxygen atoms.
b. electrons are transferred from the oxygen atoms to the carbon atoms.
c. many valence electrons are shared between the atoms.
d. a few valence electrons are shared between the atoms

Answer : The correct option is C.

Explanation :

Covalent bond : Covalent bond forms when two non-metal atom share a pair of electrons.

In the covalent bond formation of carbon dioxide, carbon and oxygen atom share four pair of electrons. The carbon atom joined by four covalent bonds to two oxygen atoms.

The valence electrons in carbon atom = 4

The valence electrons in two oxygen atom = 2(6) = 12

Therefore, these atoms are rearranged to form the bonds by the sharing of many valence electrons between the atoms.

The lewis-dot structure of carbon dioxide is shown below.

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
