Name two properties of electrons that indicate a wave-like nature

The two properties that indicate wave-like nature of an electron is its motion and electrons diffraction and interference in a beam.

Explanation:

The term diffraction refers to when a light from a point source hits an obstacle then the waves are spherical and forms a fringed image pattern.

Whereas interference refers to when two or more wave trains move on intersecting or coincident paths, then their net effect is called interference.

Therefore, it can be concluded that the two properties that indicate wave-like nature of an electron is its motion and electrons diffraction and interference in a beam.

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).
