Question: 1 / 400

What is an atom or molecule with an electrical charge?

Emulsion

An atom or molecule with an electrical charge is known as an ion. In chemistry, ions are formed when atoms gain or lose electrons, resulting in a positive or negative charge. In this case, the correct answer is B.

Emulsion, solution, and suspension are not atoms or molecules with an electrical charge. Emulsion is a mixture of two or more liquids that are normally immiscible; a solution is a homogenous mixture of one or more solutes dissolved in a solvent; and a suspension is a heterogeneous mixture in which particles settle out of a solvent over time.
