What governs the behavior of electrons?

A feature called an atomic orbital describes the wave-like behavior of a bound electron.

Explanation:

Each orbital has its own set of quantum numbers such as energy, angular momentum and angular momentum projection, and there is only a distinct set of such orbitals around the nucleus.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
