luster
streak
cleavage
question 11 (2 points)
the human body does not need minerals to survive.
true
false

Explanation:

Question 9

Atoms have a nucleus containing protons and neutrons. Electrons orbit around the nucleus, not in it. Orbitals are regions where electrons are likely to be found, not particles.

Luster (how a mineral reflects light), streak (color of a mineral in powdered form), and cleavage (tendency to break along flat surfaces) are common properties of many minerals. Double refraction (ability to split light into two rays) is a special property of some minerals like calcite.

The human body needs minerals for various functions like bone health (calcium), nerve function (sodium, potassium), etc.

Answer:

C. electron, D. orbital
