The diagram below shows the stars that are nearest to our solar system. Students were discussing this diagram and why these are the brightest stars in our sky.

Study the diagram and explain why the student C is incorrect. Student C said , “I think it’s because these stars are very close and very luminous.”

Then rewrite Students C's explanation to be correct.

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).
