Webb13 mars 2024 · Cu=+2, N=+5, O=-2. The total number of electrons that an atom acquires or loses to establish a chemical connection with another atom is known as the oxidation number, also known as the oxidation state. Simply put, an element's oxidation number is the number assigned to it in a chemical combination. Webb22 mars 2024 · What is the oxidation number of N2? zero N2 is a molecule that is the elemental form of nitrogen, and its atoms have no charge. The oxidation number for these S, K, and N atoms will be zero. In which substance does hydrogen have an oxidation number of zero? Answer is: H₂ (molecule of hydrogen). Is Cu 1 or Cu 2 more stable?
Webb13 jan. 2024 · CuSO 4. Oxidation number of Cu = +2 . Oxidation number of O = -2. CuSO 4 is a neutral molecule. ∴ Sum of the oxidation numbers of all atoms = 0. ∴ (Oxidation number of Cu) + (Oxidation number of S) + 4 × (Oxidation number of O) = 0. ∴ (+2) + Oxidation number of S + 4 × (-2) = 0. WebbOxidation number of Copper in CuH is +1 . For example CuH + HCl > CuCl + H2 It looks strange as copper lies below Hydrogen in metal activity series.
