Answer: The oxidation number of chromium in the given compound is +6 Explanation: Oxidation number is defined as the number which is assigned to the element when it gains or loose electrons.If the element gains electron, it will attain a negative oxidation state and if the element looses electrons, it will attain a positive oxidation state. Which of the following inner orbital octahedral complex ions are diamagnetic? In chemistry, a formal charge (FC) is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity. The carbon-chlorine bond will have oxidation numbers as -1 on chlorine and +1 on carbon and the carbon-hydrogen bond as -1 on carbon and +1 on hydrogen.

For monatomic ions, the oxidation number is the same as the charge on the ion. Since there are four fluorine atoms, the total oxidation number for the fluorine portion of the molecule is -4. In binary compounds (or polyatomic ions), the second element is assigned a negative oxidation number, usually the same as the charge on its monatomic ion. The formal oxidation state is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic. This means that every C-H bond will decrease the oxidation state of carbon by 1. According to rule 9, the sum total oxidation states add up to zero for C 2 H 6.
