Why is the valence of the first N in NH4NO3 3 3 and the valence of the second N 5

In NH4NO3, NH4+ is an ammonium ion, NO3- is nitrate, both of them are atomic clusters, to be seen separately, because hydrogen is +1 valence, NH4+ is +1 valence, so N is -3 valence in NH4+, because O is -2 valence, NO3- is -1 valence, so N is +5 valence in NO3-.

In k2mno4, k is +1 valence and o is -2 valence, so mn is -(1*2-2*4)=+6 valence.

NO3 is an atomic cluster, showing a negative one, and oxygen is a positive two, so N in NO3 is a positive five; NH4 is a positive one, and hydrogen is a positive one, so N in NH4 is a negative three; In K2mnO4, Mno4 is permanganate, and the whole is negative two, and oxygen is negative two, so MN is positive six.

NH4+ is +1 valence, h in ammonium is +1 valence, and n is -3 valence. no3- is -1 valence and o is -2 valence, so n is +5.

The potassium ion in KMno4 is +1 valence, the oxygen is -2 valence, and the compound should be neutral, so Mn is +6

I guess you didn't have long since you started learning chemistry in junior high school, and the specific valence of this valence has been calculated and measured by experts.

If it is explained from the perspective of junior high school, it is because NH4NO3 (ammonium nitrate) can be said to be formed by the combination of two atomic clusters, NH4 (ammonium) as a whole shows +1 valence, NO3 (nitrate) shows 1 valence as a whole, and hydrogen in junior high school only shows +1 valence in the compound, and O only shows 2 in the compound, so that the former n is 3 and the latter n is +5

And in K2mnO4 (potassium manganate), K shows positive monovalent, as another atomic group Mno4 (manganate) shows 2 valence, in the same way, O is not 2, so the Mn obtained is +6 valence.

Summary. Hello, Glad to serve you. According to the principle of the algebraic sum of the valency of the elements in the compound and the principle of zero and the valency of the elements of hydrogen and oxygen, it can be calculated:

The valency of nitrogen in NH4NO3 is +5 valence, and the valency of nitrogen in NH4 is -3 valence

The valency of NH4NO3 is.

Hello, Glad to serve you. According to the principle of the algebraic sum of the valency of the elements in the compound and the valency of hydrogen and oxygen, it can be calculated that the valency of nitrogen in NH4NO3 is +5, and the valency of nitrogen in NH4 is -3

Nh4NO3 can be divided into two atomic clusters: NH4 and NO3 Then: the valency of NH4 ions is 1 valence, each hydrogen is 1 valence, and 4 are 4 valence, so that n 4 1 is obtained, and n is 3 valence:

Similarly, NO3 ions are 1-valent and each oxygen is 2-valent.

First of all, NH4NO3 can be split into two clusters.

NH4 and NO3

Then: valency of NH4 ions.

is 1 valence, each hydrogen is 1 valence, and 4 are 4 valence.

In this way, n 4 1 can be obtained, and n is 3 valence: in the same way, no3 ions are 1 valence, each oxygen is 2 valence of Zen Touch, and 3 is 6 valence, so that n is noisy 6 1, and n is 5 valence.

So in NH4NO3 n there are two valencies, —3 and 5

Because ammonium nitrate is a salt compound, which is composed of anion and ion, ammonium ion with a positive charge of 1 unit, and locust nitrate with a negative charge of 1 unit, the valency of ammonium is +1, and the valency of nitrate is -1, in the ammonium kernel root, the valency of element h is +1 valence, let the valency of element n be x, and the valency of x+(+

N in NH3 is -3 valence.

Because h is +1 valence.

So the valency of n = -1*3 = -3 valence.

Directly is n4o6

Let n be x according to the valence of o is -2

Then 4x-2 6=0

The solution is x=3, so it is +3 valence.

The valency of H is +1 valence, and the valency of O is -2 valence, so the valency of N in Hno3 is +5 valence.

Nitric acid is a planar covalent molecule, the central nitrogen atom sp2 is hybridized, and a p orbital that does not participate in the hybridization forms a three-center, four-electron bond with two end oxygen. The hydroxyl hydrogen in nitric acid forms intramolecular hydrogen bonds with non-hydroxylated oxygen atoms, which is the main reason why nitric acid is less acidic than sulfuric acid and hydrochloric acid, and the melting and boiling point is lower.

You are right, but -1 valence is the valency of nitrate, in nitrate o is -2 valence, and o has 3, so n is +5 valence.

(+1) +x + 2)*3 = 0x = +5

no3- has a negative charge, and the two are not contradictory:

x + 2)*3 = -1

x = +5

Because oxygen is -2 valence, there are three oxygens, so n is -5 valence as follows.

Oxygen is -2 valence and three is -6, so n is +5

The valencies of n in NH no are 3 and +5 valence, respectively. Since the valency of nh + is 1 valence and h is +1 valence, let the valency of n be x, then there is x+(+1)*4=+1, and the solution is x=-3, and the valency of the other no - is -1 valence, and o is -2 valence, and let the valency of n here be y, then there is y+(-2)*3=-1, and the solution is y=+5.

What is ammonium nitrateAmmonium nitrate is an ammonium salt with the chemical formula NH4NO3. It is a colorless and odorless transparent crystal or a white crystal, which is easily soluble in water, easy to absorb moisture and agglomerate, and absorbs a lot of heat when dissolved. Decomposed by violent impact or heat, decomposed by alkali.

It is an oxidizing agent used in fertilizers and chemical raw materials.

Pure ammonium nitrate is a colorless and odorless transparent crystal or a small white particle crystal, which reacts with alkali to produce ammonia gas and absorb heat. It is deliquescent and easy to agglomerate. Soluble in water and heat absorption, soluble in acetone, ammonia, slightly soluble in ethanol, insoluble in ether.

First of all, you can divide NH4NO3 into two atomic clusters.

NH4 and NO3

Then: valency of NH4 ions.

is 1 valence, each hydrogen is 1 valence, and 4 are 4 valence.

In this way, n 4 1 is obtained, and n is 3 valence: in the same way, the no3 ion is 1 valence, and each base orange is 2 valence, and 3 is 6 valence, so that n 6 1 is obtained, and n is 5 valence.

So in NH4NO3 n there are two valencies, —3 and 5
