Can someone answer some of these? 1- What properties should an object possess in order to conform to the concept of minerals?

2- mention some of the characteristic properties of minerals.

3- what are the most common two elements in minerals?

4- suppose you have two specimens of the same hardness. Is this property enough to confirm that these two specimens are of the same mineral?

Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level.

Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

Silicate Minerals Silicon and oxygen are the two most common elements in the Earth's crust. Minerals that contain a combination of these two elements are called silicate minerals.

No because there are many physical properties of minerals that are testable with varying degrees of ease, including color, crystal form (or shape), hardness, luster (or shine), density, and cleavage or fracture (how the mineral breaks)
