Which special substances are both ionic and covalent compounds, to name a special one

There is no such thing as a substance that is both an ionic compound and a covalent compound, and it can be said that a compound has both ionic and covalent bonds, but it cannot be said to be both an ionic compound and a covalent compound.

For example, NaOH, NH4Cl, and Na2O2 are ionic compounds that have both ionic bonds and covalent health.

Ionic compounds must have ionic bonds and may have covalent bonds.

Covalent compounds only have covalent bonds.

And the aluminum chloride you are talking about is a covalent compound, and there are no ionic bonds in it.

Both ionic and covalent bonds are ionic compounds, such as, oxygenates, hydroxides, etc., are both ionic and covalent bonds, and they are all ionic compounds.

There is no ......Ionic compounds and covalent compounds are two incompatible concepts.

Ionic compounds refer to chemical compounds that contain ionic bonds.

Covalent compounds are compounds that contain only covalent bonds.

There are no such compounds. As long as it is an ionic compound, it can no longer be called a covalent compound; As long as it is a covalent compound, it can no longer be called an ionic compound. It may be that you are confusing ionic compounds, covalent compounds, with the type of chemical bonds they contain.

None: both ionic and covalent.

It can be, that is, there are no ionic bonds, and there are ionic combinations of covalent bonds.

Alkali: (except ammonia) NaOH

Oxygenates: Na2CO3 Na2SO4

Ammonium salt: NH4Cl

Sodium peroxide is also: Na2O2

For example, ammonium nitrate is an ionic compound.

Nitric acid, on the other hand, is a covalent compound.

The chemical formula is c, but it is not a single carbon atom, but a crystal made up of many carbon atoms.

Compounds containing only three elements, H, N, and O, may be ionic or covalent compounds, and this sentence is true, for example, NH Hno is an ionic compound.

Diamond has the chemical formula C, and it contains covalent bonds because of the formation of shared electron pairs between adjacent carbon atoms.

Chemical bonds cannot be formed between multiple molecules of a single atomic molecule. Because they are already stable structures.

HNO3 covalent compound.

NH4NO3 ionic compounds.

Diamond, crystalline silicon, silica, etc. are solids directly composed of atoms, in the solid, any adjacent atoms are covalently bonded together, so the melting and boiling point is relatively high, respectively, C, Si, SiO2 to represent them, but they are not molecules.

Noble gas molecules are single-atom molecules, and because each atom has reached a stable structure, there are no chemical bonds between the atoms of the noble gas molecules.

Non-metallic elements have more electrons in the outermost shell, and when they are composed of compounds, they all share electrons to form bonds, so they must be covalent compounds.

Not necessarily, counter-example: NH4NO3 (ammonium nitrate, which is an ionic compound).

There is an ionic bond between the ammonium ion and the nitrate ion in ammonium nitrate, a covalent bond between the nitrogen atom and the hydrogen atom, and a covalent bond between the nitrogen atom and the oxygen atom in the nitrate ionIt belongs to ionic compounds containing covalent bonds.

There are many similar examples, such as NH4Cl (ammonium chloride), (NH4)2SO4 (ammonium sulfate) and so on.

A compound made up of cations and anions. When active metals (such as sodium, potassium, calcium, magnesium, etc.) and active nonmetals (such as fluorine, chlorine, oxygen, sulfur, etc.) are combined with each other, the active metals lose electrons to form positively charged cations (such as Na+, K+, Ca2+, Mg2+, etc.), and active nonmetals obtain electrons to form negatively charged anions (such as F-, Cl-, O2-, S2-, etc.), and cations and anions form ionic compounds by electrostatic action. For example, sodium chloride is an ionic compound composed of positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-).

In ionic compounds, the total number of positive charges carried by cations is equal to the total number of negative charges carried by anions, and the whole compound is electrically neutral.

Ionic compounds are present in :

1. Compounds formed between reactive metals and reactive non-metallic elements.

2. Compounds formed between metal elements and acid ions. (Acid ions such as sulfate ions SO42-, nitrate ions NO3-, carbonate ions CO32-, etc.).

3. Between ammonium ions (NH4+) and acid ions, or between ammonium ions and non-metallic elements, such as NH4Cl and NH4NO3

Hello! Compounds containing only three elements, H, N, and O, may be ionic compounds or covalent compounds, this sentence is true, for example, NH is an ionic compound.

The chemical formula of the diamond stone is C, and it contains covalent bonds because of the formation of a common electron pair between adjacent carbon atoms.

Chemical bonds cannot be formed between multiple molecules of a single atomic molecule. Because they are already stable structures.

It only represents a personal opinion, don't spray if you don't like it, thank you.

For example, ammonium nitrate is an ionic compound.

Nitric acid is Zheng Qing, a valence compound of afissure clumps.

The chemical formula is C, but in fact, it is not one carbon atom, but a crystal made of many carbon atoms.

B term, which contains a covalent bond.

The compounds are not necessarily covalent compounds, such as sodium hydroxide.

There are ionic bonds and covalent destruction bonds, hydrogen and oxygen in hydroxide are combined by covalent bonds, and sodium hydroxide is an ionic valence compound, so item b is correct; a, ammonium nitrate is a compound composed entirely of non-metallic allergic residues

Covalent compounds are formed by the combination of shared electron pairs, mainly by the combination of non-metals and non-metallic elements, all acids are covalent compounds, a small number of salts are covalent compounds, non-metallic oxides are covalent compounds, and BE2Cl2, AlCl3 are covalent compounds, as a special case.

Ionic compounds are formed by the gain and loss of electrons, mainly formed by the combination of metals and non-metallic elements, all bases are ionic compounds, most salts are ionic compounds, metal oxides are ionic compounds, NH4Cl is ionic compounds, as a special case!

The melting point of ionic compounds is high, hard and brittle, and the melting point of covalent compounds is lower and the hardness is small, which is mainly related to the force, ionic compounds are bound by ionic bonds, and covalent compounds are combined by intermolecular forces. The energy of the intermolecular force is much smaller than that of ionic bonds.

Also, compounds that contain ionic bonds are definitely ionic compounds, and ionic compounds may contain covalent bonds, such as NaOH, and covalent compounds contain only covalent bonds.
