Chemistry
Answer
Alloys
Reason — A homogenous solution of a solid into another solid is called a solid solution and common metal alloys are solid solutions because an alloy is also a metal made by mixing two types of metals together.
Allotropy refers to different forms of the same element (e.g., carbon as diamond and graphite), not solutions. Isotopes are atoms of the same element with different masses, not mixtures. Isotones relate to atomic structure, not solutions.
