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

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).
