Final answer:
The question pertains to the properties of a nonmetallic mineral used to identify it, such as solubility, melting point, and color. Hard, brittle nonmetals that conduct electricity as a liquid differ from shiny, malleable, ductile metals.
Step-by-step explanation:
The question appears to be describing the properties of a nonmetallic mineral with good cleavage in four directions, which can be colorless, yellow, green, blue, or violet, and is transparent to translucent. Minerals often have characteristic properties that help in their identification, such as solubility in H2O, melting point, flammability, color, hardness, transparency, and other physical and chemical qualities.
Hard, brittle materials that conduct electricity as a liquid but not as a solid, and have high to very high melting points are typical of some nonmetallic minerals. In contrast, metals are usually shiny, malleable, ductile, and conduct heat and electricity well, with variable hardness and melting temperatures.
