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? Electrons are transferred from the carbon atom to the oxygen atoms.
Electrons are transferred from the oxygen atoms to the carbon atoms.
Many valence electrons are shared between the atoms.
A few valence electrons are shared between the atoms.

Many valence electrons are shared between the atoms.

Explanation:

For the atoms to form a covalent bond, a many of the valence electrons are shared between the atoms.

When a covalent bond is to be formed, the valence electrons which are the outermost electrons are shared between the atoms that are combining.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

i think its 100

i hope this !
