Determine the oxidation state of each of the following species. Also, another formula that if two atoms of the same element make one single molecules such as diatomics molecules are O2, N2, I2, Br2 oxidation states are zero, thus here N … Oxidation state in metals. The correct order of N-compounds in its decreasing order of oxidation states is (1) HNO3, NO, N2, NH4Cl (1) HNO 3, NO, N 2, NH 4 Cl (2) HNO 3, NO, NH 4 Cl, N 2 (3) HNO 3, … Since Br 2 is a stronger oxidant than I 2, it oxidises S of S 2 O 3 2-to a higher oxidation state of +6 and hence forms SO 4 2-ions. you should also remember that oxygen always has oxidation state of -2 unless stated otherwise. number of 1. The oxidation state is the atom's charge after ionic approximation of its bonds. 0 0. Assigning oxidation numbers to organic compounds The oxidation state of any chemically bonded carbon may be assigned by adding -1 for each more electropositive atom (H, Na, Ca, B) and +1 for each more electronegative atom (O, Cl, N, P), and 0 for each carbon atom bonded directly to the carbon of interest.
