Which term refers to a substance composed of atoms of two or more different elements joined by chemical bonds?

• A. Element
• B. Compound
• C. Mixture
• D. Solution

Answer: (B)

A substance made by chemically bonding atoms from two or more different elements is a compound. Elements are pure substances with only one kind of atom. If elements are just mixed together without bonding, you get a mixture; a solution is a homogeneous mixture where something is dissolved, but no new chemical bonds form between the elements. In a compound, the elements combine in definite proportions and form a material with properties that are different from the individual elements, and it can be separated into its elements only by chemical reactions. Examples include water (H2O) and table salt (NaCl).
