what is a compound in chemistry?

In chemistry, a compound is a substance produced when two or more chemical elements are chemically bonded together. Chemical bonds, which can be

ionic
or covalent,

are responsible to held together the atoms of different elements and the resulting compound has unique physical and chemical properties different from those of its constituent elements.

Compounds can be created through a variety of chemical reactions, including

synthesis reactions
decomposition reactions
and combustion reactions.

Examples of compound in chemistry

Examples of compounds in chemistry are given below:

Water

Sodium chloride

Methane

GlucoseA

Water

This is a compound produced by the covalent bonding of

two hydrogen atoms
and one oxygen atom.

Sodium chloride

This is an ionic compound made by the electrostatic attraction between

sodium cations (Na+) and chloride anions (Cl-).

Carbon dioxide

This is a covalent compound formed by the sharing of electrons among

one carbon atom and two oxygen atoms.

Methane

This is a molecular compound produced by the covalent bonding of one carbon atom and four hydrogen atoms.

GlucoseA

This is an organic compound that is a simple sugar and an vital energy source for living organisms.

Calcium carbonate

This is an ionic compound found in

Rocks
Shells
and pearls,

and is formed by the reaction between

calcium ions (Ca2+)

and carbonate ions (CO32-).

Types Of Compound

Compounds have many types in chemistry such as given below:

Ionic compounds:

These are compounds produced by the electrostatic attraction between positively and negatively charged ions. Examples include

sodium chloride
and calcium carbonate.

Covalent compounds:

These are compounds produced by the sharing of electrons between atoms. Examples include

water
and carbon dioxide

Molecular compounds:

These are covalent compounds formed of molecules, which are groups of atoms held together by covalent bonds. Examples include

methane
and ammonia.

Organic compounds:

These are compounds that have carbon atoms bonded to hydrogen atoms and may contain other elements such as

Oxygen
Nitrogen
and sulfur.

Examples include

Carbohydrates
Proteins
and fats.

Inorganic compounds:

These are compounds that do not have carbon-hydrogen bonds. Examples include

Salts
Acids
and bases.

Metallic compounds:

These are compounds produced among metal atoms. Examples include

copper sulfate (CuSO4)
and iron oxide (Fe2O3).
