Explain why electrons are shared equally in ozone, O3, and unequally in carbon dioxide, CO2?

Answer 1

because in ozone structure the three atoms of Oxygen have the same electron affinity so the electrons are shared equally
in carbon dioxide structure, the electron affiinity of C is less than that of O so, the electrons are shared unequally ( they are nearer to O than to C )

Answer 2

Covalent Bonds-Covalent bonding is a form of chemical bonding between 2 non steel atoms that's characterised via the sharing of pairs of electrons between atoms and different covalent bonds. A covalent bond is shaped between 2 non-metals that have comparable electronegativities. Neither atom is "reliable" sufficient to charm to electrons from the different. For stabilization, they proportion their electrons from outer molecular orbit with others Ionic Bonds-Ionic bond, additionally customary as electrovalent bond is a form of bond shaped from the electrostatic charm between oppositely charged ions in a chemical compound. a majority of those bonds happen specifically between a steel and a non steel atom. An ionic bond is shaped between a metallic and a non-metallic. Non-metals(-ve ion) are "stronger" than the metallic(+ve ion) and can get electrons very incredibly from the metallic. those 2 opposite ions charm to a minimum of one yet another and style the ionic bond. EG: Covalent: Methane (CH4), Hydro Chloric acid (HCL), which components are all nonmetals Ionic: Sodium chloride (NaCl), Sulphuric Acid (H2SO4 ) and so on.
