-3. To answer this kind of question, with rare exceptions, assume oxygen is -2 and hydrogen is +1. There are then 5 positive charges from these elements and only two negative charges, requiring nitrogen to have three additional negative charges to achieve electrical neutrality for the compound as a whole.
The oxidation state of an individual nitrogen atom in CaCO3 is +4. In CaCO3, nitrogen is present in the carbonate ion (CO3)2-, and since each oxygen atom in the carbonate ion has an oxidation state of -2, the carbon atom must have an oxidation state of +4 to balance the charge.
The oxidation state of the nitrogen atom in HNO3 is +5. This is because oxygen is typically assigned an oxidation state of -2, and hydrogen is +1. In HNO3, the total oxidation states of the hydrogen and oxygen atoms sum to zero, leaving nitrogen with an oxidation state of +5 to balance the charge.
The oxidation state of N in NH4+ is -3. Nitrogen typically has an oxidation state of -3 when it is in the ammonium ion (NH4+).
Ammonia and organic Amines, contain N in -3oxidation state
Gaining electrons lead to decrease in oxidation state.
The oxidation state of an individual nitrogen atom in CaCO3 is +4. In CaCO3, nitrogen is present in the carbonate ion (CO3)2-, and since each oxygen atom in the carbonate ion has an oxidation state of -2, the carbon atom must have an oxidation state of +4 to balance the charge.
In KNO3, the nitrogen atom has an oxidation state of +5. This is because potassium (K) is in Group 1 and has an oxidation state of +1, and oxygen (O) is in Group 6 and has an oxidation state of -2. To balance the charges, nitrogen must have an oxidation state of +5.
The oxidation state of the nitrogen atom in HNO3 is +5. This is because oxygen is typically assigned an oxidation state of -2, and hydrogen is +1. In HNO3, the total oxidation states of the hydrogen and oxygen atoms sum to zero, leaving nitrogen with an oxidation state of +5 to balance the charge.
The oxidation state of nitrogen in HNO3 is +5 because oxygen is assigned an oxidation state of -2 and hydrogen is assigned an oxidation state of +1. The sum of the oxidation states must equal the overall charge of the molecule (zero in this case for a neutral compound).
In NH4F, nitrogen has an oxidation state of -3, hydrogen has an oxidation state of +1, and fluorine has an oxidation state of -1.
The oxidation state of NO is +1. This is because nitrogen is in Group 15 of the periodic table and typically has an oxidation state of -3. In NO, oxygen is more electronegative than nitrogen, causing nitrogen to have a formal oxidation state of +1 to balance the charge.
The oxidation state of nitrogen in NH4+ is -3.
This answer is -1.To find this answer:Oxygen has an oxidation number of -2.Hydrogen has an oxidation number of +1, and there are 3 of themyou want to get the oxidation numbers to add up to 0, so it would be neutral.-2 + 3(+1) = +1Now, to get this to equal zero, it means that N has to be -1.
-3
The oxidation state of nitrogen (N) in NH4+ is -3. Nitrogen usually has a -3 oxidation state in ammonium ion (NH4+) as hydrogen is typically considered to have +1 oxidation state and there are four hydrogen atoms bonded to nitrogen in NH4+.
In NH3 the oxidation state of Nitrogen is -3. It has 3 extra electrons in three polar covalent bonds, 'donated' from three bonded hydrogen atoms. Hydrogen has an oxidation state of +1 in this compound.
The oxidation state of Nitrogen in NH2NH2 is -2. This is because each hydrogen atom has an oxidation state of +1 and there are two hydrogen atoms bonded to each nitrogen atom in NH2NH2. Since the overall charge of NH2NH2 is neutral, the nitrogen atoms must have an oxidation state of -2 to balance the positive charges of the hydrogen atoms.
