Oxygen is -2, unless in peroxides. Since nitrogen is more electronegative than hydrogen, hydrogen will occupy a #+1# charge. NO2^- == +3. Lv 6. An actual charge has the number first, then the sign. As Nitrogen is in 2nd period in the modern periodic table, principal quantum number being n=2, the Azimuthual Quantum numbers = 0 to n-1 for Nitrogen it ranges from 0 to 1. 2. Therefore,the oxidation number of Nitrogen is -3. In this way the very endothermic reduction of N2 direct to NA has been circumvented. each of these hydrogen atoms will form a covalent bond with a nitrogen atom. O in compounds = -2 normally. I'll let you order them. Rais. If the molecule is neutral, all of the oxidation numbers have to add up to zero. Write a balanced equation for process of converting N 2-> NH 3. | EduRev JEE Question is disucussed on EduRev Study Group by 110 JEE Students. Relevance . Overall, N2 is the oxidizing agent. Let #x# be the oxidation number of #N# in #NH_4^+#.
