What is the valence of oxygen in rubidium trioxide? What is the valence of oxygen in ferric tetroxid

Rubidium trioxide is RBO3

In RBO3 the oxygen element is a covalent bond between two pairs, three O are co-manifest -1 valence, and the average valency without oxygen atom is -1 3, but from the point of view of oxidation number, the oxidation number of two oxygen is 0, and the remaining one is -1

Rubidium is an alkali metal element, and sodium oxide is a class.

Sodium oxide Na2O, oxygen is -2 valence, while in RuO3 the oxygen element is a covalent bond between two pairs and three O is co-manifest -1

Rubidium, atomic number 37, atomic weight, rare alkali metal element. The name of the element is derived from two distinct red lines on the rubidium spectrum, which originally means "crimson" in Latin. In 1861, German chemists Bunsen and Kirchhoff discovered rubidium while studying the spectra of lepidolite samples.

Rubidium is a dispersed element, difficult to form a mineral independently, often symbiotic with potassium, the main minerals are lepidolite and carnallite. For example, there are two natural isotopes: rubidium-85 and rubidium-87, of which rubidium-87 is radioactive.

Rubidium is a lively light metal with a low melting point, a melting point, a boiling point of 686 °C, and a density of gram cm.

Rubidium is chemically similar to potassium but is more reactive than potassium; The flame of volatile rubidium salts is purple-red, which can be used to qualitatively test rubidium; Rubidium metal can be prepared by reducing rubidium chloride by calcium, magnesium, etc.

Rubidium metal is easy to emit electrons under the action of light, which can be used to make photocells.

1. It is called rubidium ozooxide, which is red near liquid.

Is rbo3 there I haven't seen it I've only seen rubidium monoxide, rubidium peroxide, rubidium trioxide, rubidium tetroxide.

The valency of oxygen is very special, generally -2 and 0 valence. Whereas, oxygen is usually -1 valence in peroxides, -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 sold at high temperature and oxidized in pure oxygen to form platinum dioxide, ** is generally considered to be unable to react with oxygen, but there are compounds such as gold oxide and gold hydroxide, of which gold is +3 valence; Oxygen cannot react with chlorine, bromine, iodine, but ozone can oxidize them.

In ferric tetroxide, two irons are +3 valent and the other is +2 valent. Because ferric oxide is synthesized from one iron oxide and one ferric oxide, ferric oxide is a special case in which it has two different valencies of iron.

Ferric oxide is the only iron compound that can be magnetized in secondary school. Ferric oxide contains Fe2+ and Fe3+, and X-ray diffraction experiments show that ferric tetroxide has a trans spinel structure, and the metaferrite ion FeO22- is never present in the crystal. Ferric oxide, also known as magnetic iron oxide, iron oxide black, magnet, magnet, magnetite, magnetite Qimeng, the natural mineral type is magnetite.

In oxides, O is -2 valence, peroxide grinding (O2 2-) is -1 valence, Superoxide (O2 -) is -1 2 valence, O3 -) is -1 3 valence.

The valency of ho does not change with the number of charges they have in an ion or molecule.

Generally speaking. Except for hydrogen and oxygen, h is +1

o are all -2, such as water, sulfuric acid, carbon dioxide... Wait a minute.

1. In elemental matter, the oxidation number of the element is zero.

2. In ionic compounds, the oxidation number of an element atom is equal to the charge number of the element's monoatomic ions.

3. In covalent compounds whose structure is known, the common electron pairs belonging to two atoms are placed.

When assigned to the atom that is more electronegative of the two atoms, the number of apparent charges left on the two atoms is their oxidation number. For example, in H2O, the oxidation number of the oxygen atom is -2 and that of hydrogen is +1.

For a covalent bond between two atoms of the same element, the oxidation number of that element is zero. If an element in the compound has two or more covalent bonds, the oxidation number of the element is the algebraic sum of the oxidation numbers exhibited by the respective bonds.

4. In covalent compounds with unknown structure, the oxidation number of an element can be calculated from the oxidation number of other elements of the compound according to the following provision, which is: the total charge number of a molecule or complex ion is equal to the algebraic sum of the oxidation numbers of each element in it.

The valency of oxygen depends on the compound in which the oxygen atom is involved. Normally, the valency of oxygen is -2. However, it is also possible that the valency of the oxygen atom in some organic wax purities is higher, reaching -1 or higher.

If you can give me a thumbs up! Thank you!

OxygenValencyVery special, generally -2 and 0 valence.

And oxygen in peroxide.

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.

For example, platinum is oxidized in pure oxygen at high temperature to form platinum dioxide, which 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.

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.

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.

1. The most common valency of oxygen is -2 valence.

2. When oxygen and fluorine form compounds, oxygen shows positive valence, such as: O in of2 is +2 valence.

3. When oxygen is bonded with other elements and self-bonded with oxygen elements, oxygen shows other negative valences. For example, oxygen in H2O2 and Na2O2 presents -1 valence.

4. Similar to 3, oxygen has other negative valences, such as: -1 2 valence in KO2 (K2O4), -1 3 valence in RBO3 (RB2O6) and so on.

The valency of oxygen is -2 valent in the compound.

However, if it is elemental oxygen, it is 0 valence.

Sometimes, however, oxygen is also -1 valent.

Be careful.

You can't go wrong.
