A substance formed by chemically uniting two elements is known as a/an?

A substance that is formed by the chemical unification of two or more elements is referred to as a compound. Compounds result from a chemical reaction in which elements bond together through various types of chemical bonds, such as covalent or ionic bonds. For instance, water (H2O) is a compound made up of hydrogen and oxygen atoms that are chemically bonded together.

In contrast, a mixture consists of two or more substances that are physically combined but not chemically bonded. Each substance in a mixture retains its own properties and can be separated by physical means. An element is a pure substance made of only one type of atom and cannot be broken down into simpler substances, while a solution is a homogeneous mixture where one substance (the solute) is dissolved in another (the solvent). Therefore, the designation of a compound accurately reflects the nature of its formation through chemical unification of elements.
