Answer:
Many valence electrons are shared between the atoms.
Step-by-step 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.
- Carbon is made up of 4 valence electrons.
- Oxygen is made up of 6 valence electrons
- For both atoms to be isoelectronic with the noble gases, carbon shares all of its 4 electrons with oxygen.
- Oxygen bonds shares 4 electrons using two of its atom with the carbon.
