Which substance is not both a metal and mixture but an element?

Answer and explanation

Correct answer: Oxygen

The governing concept is the classification of matter into elements, compounds, and mixtures, with metals and non-metals being types of elements. Oxygen consists only of oxygen atoms and therefore is an element; it is specifically a non-metal. Brass is a homogeneous mixture, or alloy, of mainly copper and zinc. Air is a mixture of gases, principally nitrogen and oxygen, while salt water is a mixture of salt dissolved in water. Thus, option C is the only element. The word “metal” is a distractor because oxygen is not a metal, but the question asks for an element, not necessarily a metal.
