Atoms that are the same form a(n):

Atoms that are the same form a(n):

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

Answer: (B)

Atoms that are the same form an element because an element is a pure substance made of one kind of atom, all sharing the same number of protons. When all the atoms are identical, you have an elemental substance, like O2 or N2. A mixture is a physical blend of two or more substances without chemical bonding, so the atoms can be from different elements. An emulsion is a specific type of mixture of two immiscible liquids stabilized together. A compound arises when different elements bond chemically to form a new substance with properties different from its elements. So, identical atoms define an element.
