Question

Quizplus · Accepted Answer

Alloys are mixtures of two or more metals, or a metal and a non-metal, where the atomic ratios of the constituent elements can vary widely. In contrast, compounds are made up of two or more elements in a fixed, definite proportion. The other options are incorrect; not all alloys contain carbon, iron or transition elements, and not all alloys have semiconductor properties.
