Asample of matter was given the following description: the sample of the pure substance is blue in color with an octahedral shape with very distinct edges. into which of the classification would this sample belong?

A crystalline solid

Explanation:

Most solids form with a regular arrangement of their particles because the overall attractive interactions between particles are maximized, and the total intermolecular energy is minimized, when the particles pack in the most efficient manner. The regular arrangement at an atomic level is often reflected at a macroscopic level.  Liquids dont use to have this kind of arrangements or shapes.

Chemical reaction is clearly incorrect.

Product is the end result of a chemical reaction.

Compound is molecules joined together.

Therefore, I would probably say solution.
