The atomic number for nitrogen is 7, meaning that it has 7 protons. In order for it to remain as nitrogen, the number of protons in it must always be 7. If, for example, the number of protons were to increase to 8, it would no longer be nitrogen; it would then be oxygen.
The sum of oxidation numbers in a neutral compound is always zero. (Note that in order for this to be true, the oxidation number of each type of atom present must by multiplied by the number of such atoms present in the formula unit for the compound before the addition is performed.)
Oxygen almost always keeps an oxidation number of -2. Since the overall ion has a charge of -1 you just have to balance the ion. 2*-2 for the oxygen = - 4 In order for the overall charge to be -1, the chlorine must have a +3 oxidation numbers.
The group I-A and III-A group have both positive and negative oxidation state . In I-A group H (hydrogen) has negative oxidation state and positive oxidation state.In III-A group B(boron) performs both positive and negative oxidation states. RGUKT IIIT NUZVID: N091528
The oxidation number of chromium in Cr2O7 is +7. The oxidation number of oxygen is -2, so 7 O atoms times -2 = -14. In order to balance the -14 on the oxygen atom, each chromium atom must have an oxidation number of +7, because 2 Cr atoms times +7 equals +14.
The atomic number for nitrogen is 7, meaning that it has 7 protons. In order for it to remain as nitrogen, the number of protons in it must always be 7. If, for example, the number of protons were to increase to 8, it would no longer be nitrogen; it would then be oxygen.
MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
MnO2: oxidation number +4KMnO4: oxidation number +7
O = N - Br...... |......O5 + 2(6) + 7 = 24 electronsThere are two "resonance" structures. This means that the bond order for the NO bonds is 1.5.

Nitrogen's atomic number is 7. Therefore, it has 7 protons, all of which are positively charged. In order to be neutral then, nitrogen must also have 7 electrons in it.
when the food is exposed to oxygen for a long time rancidity occurs. for example, let us take the chips packet ; the packet is filled with nitrogen in order to prevent oxidation.
The sum of oxidation numbers in a neutral compound is always zero. (Note that in order for this to be true, the oxidation number of each type of atom present must by multiplied by the number of such atoms present in the formula unit for the compound before the addition is performed.)
+5. In oxyacids, oxygen has an oxidation state of -2 and hydrogen an oxidation state of +1. Therefore, the single chlorine atom must have an oxidation state of +5 for the total oxidation states to add to zero.+5. In oxyacids, oxygen has an oxidation state of -2 and hydrogen an oxidation state of +1
In order to maintain, electrical neutrality, the number of electrons will also increase as the number of protons increases.
Oxygen almost always keeps an oxidation number of -2. Since the overall ion has a charge of -1 you just have to balance the ion. 2*-2 for the oxygen = - 4 In order for the overall charge to be -1, the chlorine must have a +3 oxidation numbers.
