Final answer:
Mixtures can be separated by physical means and include both homogeneous and heterogeneous combinations of substances, whereas elements, compounds, and radicals are pure substances that require chemical processes to be separated.
Step-by-step explanation:
The compound that can be separated by physical means is a mixture. Mixtures are physical combinations of two or more substances that can be separated by physical processes such as filtration, distillation, or evaporation. In contrast, an element is a pure substance made of only one type of atom, a compound is a substance composed of two or more elements chemically bonded, and a radical is a group of atoms that acts as a single entity in a chemical reaction and cannot be separated by physical means.
