How many types of bonding bonds are there between atoms? What are the characteristics of each?

There are ionic bonds, covalent bonds.

Metallic bonds, but also molecular bonds (van der Waals bonds), hydrogen bonds.

and so on. Ionic bonds: are made up of positive ions.

and negative ions are attracted to each other by electrostatic attraction; At the same time, when they are very close together, repulsion occurs, and the gravitational and repulsive forces are equal, forming a stable ionic bond. Ionic bonds tend to form between metals and non-metals. The binding force of ionic bonds is large, so usually ionic crystals have high hardness, high strength, and coefficient of thermal expansion.

Small, but brittle. It is difficult for ionic bonds to produce electrons that can move freely, so ionic crystals are good insulators.

Covalent bonds: are chemical bonds.

A type in which two or more atoms use their outer electrons together to ideally reach a state of electron saturation to form a relatively stable chemical structure called a covalent bond, or a covalent bond is an interaction formed between atoms by sharing electron pairs. Its essence is that after the atomic orbitals overlap, there is a high probability that it will appear in the nuclei of two atoms.

The electrical interaction between the electrons and the two nuclei.

Metallic bonds: Formed by a combination of electrostatic attraction between free electrons and metal ions arranged in a lattice shape. In metal crystals, free electrons move through and are not specific to a metal atom but are common to the entire metal crystal.

These free electrons interact with all metal ions. Metallic bonds are not directional, and crystals formed from metallic bonds usually have good electrical conductivity due to the presence of a large number of free electrons in metallic bonds.

Molecular bond: consists of the force between molecules (van der Waals force.

The formed crystals have low melting point, low boiling point, low hardness, and easy compressibility due to the weak molecular bonds.

Hydrogen bonding: Hydrogen atoms are covalently bonded to the electronegative atom x, and if they are close to the atom y (o f n, etc.) with large electronegativity and small radius, hydrogen is used as the medium between x and y to generate x-h....A special intermolecular or intramolecular interaction in the form of y, called hydrogen bonding.

There are five types of atomic bonds: ionic bonds, covalent bonds, metallic bonds, molecular bonds (van der Waals bonds), and hydrogen bonds.

Chemical bond is a general term for the strong interaction force between two or more adjacent atoms (or ions) within a pure molecule or crystal. The force that binds ions or atoms together is known as chemical bonding.

Ionic bonds, covalent bonds, and metallic bonds have different causes, and ionic bonds are formed by electrostatic action through the transfer of electrons between atoms to form positive and negative ions. The cause of covalent bonds is more complex, Lewis theory believes that covalent bonds are formed by the sharing of one or more pairs of electrons between atoms, and other explanations include valence bond theory, valence shell electron mutual exclusion theory, molecular orbital theory and hybrid orbital theory. A metallic bond is a modified covalent bond that is formed by multiple atoms sharing some free-flowing electrons.

Classification of chemical bonds:

In a water molecule, 2 hydrogen atoms and 1 oxygen atom are chemically bonded to form a water molecule. Since the nucleus is positively charged and the electrons are negatively charged, we can say that all chemical bonds are formed as a result of the simultaneous attraction of electrons to two or more nuclei. There are 3 types of chemical bonds, namely ionic bonds, covalent bonds, and metallic bonds (hydrogen bonds are not chemical bonds, it is a type of intermolecular force).

The atoms in the organic molecule rely mainly on covalent bonds.

Connected, covalent bonds are formed between them by sharing electron pairs.

Organic matter is mainly formed by hydrocarbons and hydrogen, and may contain oxygen, nitrogen, sulfur, phosphorus, halogens and other elements. Its atoms are mainly connected to each other by covalent bonds, and there are also a small number of ionic bonds, such as amino acids.

Now the main discussion is about covalent bonds.

A single bond is a covalent bond formed by two atoms sharing a pair of electrons in an organic compound, and after being hybridized by an orbital, the covalent bond formed by a head pair becomes called sigma.

Key. A double bond is a type of chemical bond commonly found in organic compounds.

Two pairs of electrons are shared between two atoms. A double bond cannot simply be seen as a combination of two single bonds, but through orbital hybridization, a pair of electrons forms a sigma bond in a head-to-head manner, and a pair of electrons forms a pie bond in a side-to-shoulder manner.

Three bonds. A triple bond is a covalent bond formed between organic atoms by sharing three pairs of electrons. The triple bond cannot be simply regarded as three single bonds, but a covalent bond formed by a sigma bond and two pie bonds.

Only the two elements of carbon and carbon, and carbon and nitrogen, will form a triple bond.

A large pie bond, an aromatic organic substance, forms a large chemical bond in the shape of a ring by sharing multiple pairs of electrons.

The above are the main forms of covalent bond formation by atoms in organic compounds.

Covalent bonds are formed between atoms by sharing electron pairs.

For example: h-h cl-cl

h-o-h, h-cl, etc.

1.The bonding particles of ionic bonds are anion and cation.

2.The essence of ionic bonding is electrostatic action.

3.Conditions for the formation of ionic bonds:

Compound between reactive metallic elements (IA, IIA) and active non-metallic elements (via, VIIA). Such as: NaCl, MGO, CaCl2

Salts formed by active metal cations and acid ions. Such as: K2CO3, Na2SO4

Salt formed by ammonium ions (NH4+) and acid ions. Such as (NH4)2SO4, NH4NO3, NH4CL

A base formed by active metal cations and hydroxide ions. Such as Ba(OH)2, NaOH

Very reactive metals react with hydrogen to produce hydrides such as Na, K, Ca, and H.

Thank you.

Atoms form molecules through covalent bonds.

When two atoms have a similar ability to attract electrons, they cannot completely give or get electrons, so they form bonds by sharing electron pairs, that is, each atom produces an electron to form an electron pair. This one is a covalent bond.

When there is a big difference in the energy shield force that attracts electrons, one Qing does not lose electrons, and the other gets electrons, forming anions and cations, and then attracting them into bonds by static electricity, which is ionic bonds.

When a covalent bond is formed between two atoms, the first covalent bond must be formed. () Potato stoves.

a.That's right. b.Mistake.

Correct answer: Correct.

When the following auspicious pairs bond atoms, the maximum ionic nature of the bond is ().

Sell false f correct and old answer: c

Bonding characteristics of the material: atom = nucleus (+) electron (-) due to the outer orbital of the atom by releasing or receiving electrons, positive and negative ions are formed; or to achieve relative stability of the electronic configuration by means of shared electrons.

Materials composed of metallic bonds generally have a crystalline structure with regular atomic arrangement; In a covalent crystal, the atoms are adjacent to each other at a certain angle, and there is a definite orientation between the bonds;

Relying on the atom packing method of ionic bond arrangement, positive ions and negative ions attract each other due to electrostatic attraction, and when they are in full contact, they will produce repulsion, and when the gravitational force and repulsion force are equal, a stable ionic bond is formed, so the atoms are arranged according to long-range ordered rules.

Molecular bonds and hydrogen bonds are both physical bonds, and physical bonds do not affect the arrangement of atoms but affect physical properties, such as neutral molecules and inert aerosol atoms are condensed into liquids or solids by van der Waals force.
