The substance with the chemical formula CO 3 goes by the name carbonate.Carbonate is made of 1 atom of carbon and 3 atoms of oxygen and has an electric charge of −2.This negative charge means that a single ion of carbonate has 2 more electrons than protons. Note that this charge distribution is a formalism, and the molecule is certainly a neutral entity. #:C-=O:# as written bears a formal negative charge on the carbon, and a formal positive charge on the oxygen. Explanation: Some Lewis structures of carbon monoxide depict formal charges. The formal charge of the carbon monoxide molecule is ZERO. What is the formal charge of carbon monoxide? So to find a formal charge for carbon, the formal charge is equal to the number of valence electrons in the free atom, or the number of valence electrons that carbon is supposed to have. We can calculate it as follows: Formal charge= 6-2-(1/2 ×6) = +1. For finding out the formal charge of an element in a compound, there is this formula: The Lewis structure of CO is as follows: Refer to the structure. Carbon has an electron configuration of 1s22s22p2 this means that carbon has four valence electrons 2s22p4. The octet rule is the understanding that most atoms seek to gain stability in their outer most energy level by filling the s and p orbitals of the highest energy level with eight electrons. The Hybrid Resonance forms show the different Lewis structures with the electron been delocalized. ![]() Every carbon, nitrogen, oxygen, and fluorine atom in this molecule has a full octet.Ī carbon with a negative charge is the least favorable conformation for the molecule to exist, so the last resonance form contributes very little for the stability of the Ion. When one of these atoms has less than eight valence electrons it has an open octet. ![]() Octet rule: The concept that compounds containing carbon, nitrogen, oxygen, and fluorine are more stable if these atoms have eight valence electrons. These 6 protons add up to a +6 charge, but carbon also has 6 electrons too, which supply a -6 charge, leading to no overall charge. that’s why, its charge is 4⁺.įor example, carbon has 6 protons, we know this because the atomic number (lower number on the periodic table) for carbon is 6. it shares its valence electrons with other atoms and forms covalent bonds. ![]() carbon can lose or gain 4 electrons in order to complete its octet. Ĭarbon atom has 4 electrons in its valence shell or its outermost shell. So the total charge of the nucleus of a carbon atom is +6.
