Oxygen in ozone is several valents, and oxygen is generally several valents.

The valency of the three oxygen atoms in ozone is one +2 3 and two -1 3 respectively.

Because a large PAI bond is formed between the 3 O's (the orbital is 3 and the number of electrons is 4), and the 4 electrons cannot be evenly distributed among the 3 orbitals (the molecule is not perfectly symmetrical at all times), so there is a small dipole moment, and there is a very small polarity).

O3 is the only polar element, in the O3 structure of the ozone molecule, the hybrid state of the central O atom is Sp2, in which there are two Sp2 hybrid orbitals each with one electron, which forms a bond with the two end group O atoms respectively, the unhybridized P orbital has a pair of electrons, and the unpaired electrons of the two O atoms at the lower end group form a three-center four-electron bond.

In the O3 molecule, the O atom adopts a hybrid sp2, and the apical O atom has a lone electron pair in addition to two sigma bonds with the other two O atoms.

The other two O atoms each have two pairs of lone electron pairs.

Therefore, the valency of the three oxygen atoms in ozone is one +2 3 and two -1 3 respectively.

In fact, I think that strictly speaking, the valence state in ozone is not 0 valence, because they form a large PAI bond, the electrons move, resonate, or the electrons will be shifted by external interference factors, so the valence state is different. The specific number of electrons offset, the specific situation is analyzed, and the inorganic problem can be regarded as 0 valence. The organic question needs to consider the valence.

Involved in the mechanism of the electron process. Therefore, if you simply cope with the exam, you can mostly have 0 price on the inorganic questions, and you have to analyze it organically. Generally, oxygen at both ends, one is positive 1 valence, and the other is negative 1 valence.

Specifically, it is necessary to analyze it on a case-by-case basis.

Yes, the elemental quality is 0 and will never change.

The valency of O in oxygen O2 is 0Because it's elemental.

The valency of O in the molecule is mainly negative bivalent such as carbon dioxide, and negative bivalent such as hydrogen peroxide.

And we don't say what the valency of oxygen is, but the valency of oxygen atoms in oxygen, and the valency is only for a certain atom, not a molecule.

Satisfied with the praise.

1l error.

The valencies (integer oxidation numbers) of oxygen found so far in elemental and compound compounds are as follows:

0：o2、hof。

2: Oxides in the narrow sense such as cuo.

1: Peroxides, such as H2O2, Na2O2.

1：o2f2。

2：of2。

The fractional oxidation number has:

1 2: The average oxidation number of superoxides (e.g., KO2).

2 3 and -1 3: O3 (0 is just the average oxidation number).

1 3: The average oxidation number of ozonized oxides (e.g., NaO3).

1 2: (O2)+ compounds, such as O2PTF6 (this compound directly led to the discovery of a truly noble gas compound).

In addition, there are non-integer ratio oxides, which generally range from 0 to 2. It is of little significance to discuss the oxidation number of oxygen in these substances.

Chemicals containing more than +2 valence oxygen have not been discovered. It is generally believed that due to the small atomic radius, the compound tension of the obtained ** oxygen is very large, and the stable +6 valence oxygen compound cannot be obtained by chemical methods.

The stool of oxygen is valent.

Very special, generally -2 and 0 valence. And oxygen in peroxide.

It is usually -1 valence in superoxide, -1 2 in superoxide, and -1 3 in spring wax ozonion, where the valency is called the apparent valency.

All metals except ** can react with oxygen to form metal oxides, such as platinum is oxidized in pure oxygen at high temperature to form platinum dioxide, ** is generally considered to be unable to react with oxygen, but there are compounds such as gold trioxide and gold hydroxide, of which gold is +3 valence; Oxygen cannot react with chlorine, bromine, iodine, but ozone can oxidize them.

Valency of oxygen.

It is usually -1 valence in , -1 2 in superoxides, and -1 3 in ozonoxides, and the valency here is known as the apparent valency.

All metals except ** can react with oxygen to form metal oxides, such as platinum bench is oxidized in pure oxygen at high temperature to form platinum dioxide, ** is generally considered to be unable to react with oxygen, but there are compounds such as gold trioxide and gold hydroxide, of which gold is +3 valence; Oxygen cannot react with chlorine, bromine, iodine, but ozone can oxidize them.

。In ozone, due to the presence of large p-bonds, three oxygen share four electrons, so each oxygen has 4 3 electrons, so in the amusement of the heart oxygen atom.

The valence state is (2-4 3)=2 3, and the valence state of the fundamental oxygen atom at the end of the beat is (1-4 3)=-1 3.

So ozone is a polar molecule.

Diamagnetism. Mountain grip.

In fact, it can be assumed that the valence limb number of oxygen in ozone dispersion is zero, because there is no question of whose electrons are attracted to whom.

However, ozone has 34 major bonds, and one oxygen provides two electrons, and the other two donate one electron each.

To put it simply, one oxygen in O3 is +two-thirds, and two oxygens are -one-third.

I think it should also be 0 price. Isn't ozone a molecule03? How can a molecule have positive and negative valence......

The valency of 3 oxygen atoms in ozone.

One +2 3, two - 1 3

Because a large PAI bond is formed between the 3 O's (the orbital is 3 and the number of electrons is 4), and the 4 electrons cannot be evenly distributed among the 3 orbitals (the molecule is not perfectly symmetrical at all times).

So there is a very small dipole moment.

There is also very little polarity)

O3 is the only element that has polarity.

In the O3 structure of the ozone molecule, the hybrid state of the central O atom is Sp2, in which there are two Sp2 hybrid wide-nucleated orbitals each with one electron, which form bonds with the two end groups of O atoms respectively, the unhybridized P orbital has a pair of electrons, and the unpaired electrons of the two O atoms of the lower end group of it form a three-center four-electron bond.

In the O3 molecule, the O atom takes a hybrid sp2, and the top O atom is excavated with the other two O atoms to form two sigma.

Outside the key, there is also a pair of lone electron pairs.

The other two O atoms each have two pairs of lone electron pairs.

Therefore, the valency of the three oxygen atoms in ozone is one +2 3 and two -1 3 respectively.

Monotheistic general speaking, a trip to the spine to a ozone generator, should be around 2-3 thousand no.

Oxygen. Valency.

Very special, generally -2 and 0 valence. And oxygen is in.

Peroxide. Medium is usually -1 valence, in.

Superoxide. -1 2, ozonated.

The middle oxygen is -1 3 and the valency here is known as the apparent valency.

All metals except ** can occur with oxygen.

Reaction generation. Metal oxides.

For example, platinum is oxidized in pure oxygen at high temperatures.

Platinum dioxide. **It is generally believed that it cannot react with oxygen, but there is.

Gold trioxide.

And. Gold hydroxide.

and other compounds, of which gold is +3 valence; Oxygen does not react with chlorine, bromine, or iodine, but ozone can oxidize them.
