Concept #3 Quiz
Choose the best possible answer to the following questions about Key Concept 3 "Building minerals: Atomic structure and factors of crystal form."

This activity contains 8 questions.

Minerals may form a crystal based upon their atomic structure. What controls the atomic structure in a mineral?

The rock in which it is found.The number of atoms in the mineral.The size of the atoms in the mineral.An array of atoms bonded together.

All of the following are factors that determine the atomic structure of a mineral except _______.

relative sizes of atoms and their proportionsphysical propertieschemical compositionenvironment of formation

The crystal shape and atomic structure of the minerals galena (see figure above) and halite are related by which of the following?

They have the same elements, but different structures.They have the same structure, but by different elements.They have different structures, but by the same elements.They have different structures and the same elements.

Polymorphs are two or more minerals that have the same ______ but different ______.

mass, mineral groupingatomic structure, chemical compositionchemical structure, atomic compositionchemical composition, atomic structure

Though both are polymorphs, diamond and graphite are different minerals because of each of the following except _______.

They have different atomic structures.They have different chemical compositions.They have different atomic bonding styles.They formed in different environments.

	Galena and halite have the same chemical composition and different crystalline structures.
	True False

What makes one mineral different from another that allows us to distinguish them physically?

A unique set of physical properties.Similar hardness and cleavage, or nearly so.A non-unique set of physical properties.Some similar physical properties.

What makes one mineral different from another that allows us to distinguish them chemically?

Distinct pressure and temperature conditions of formation.Distinct crystal structure controlled by bonding.Distinct chemistry.All of these.
