What do we call a substance made from two or more elements chemically bonded together?

The term used to describe a substance made from two or more elements chemically bonded together is a compound. Compounds are formed through chemical reactions, where elements combine in fixed proportions and their individual properties change to create a new substance with its own unique characteristics.

For instance, water (H2O) is a compound formed from the elements hydrogen and oxygen. These elements are chemically bonded in a specific ratio, resulting in a substance that has distinct properties separate from those of hydrogen and oxygen.

The distinction between a compound and other types of substances, such as elements, mixtures, or solutions, is crucial. An element refers to a pure substance that cannot be broken down into simpler substances, while a mixture consists of two or more substances that are not chemically bonded and can retain their individual properties. A solution is specifically a type of mixture where one substance (the solute) is dissolved in another (the solvent), typically resulting in a homogeneous mixture.

Thus, the definition of a compound clearly aligns with the understanding that it is formed through the chemical bonding of multiple elements, distinguishing it from mixtures or solutions.
