1. CH, Lewis structure

Explanation:

Separately, the Carbon has 4 valence electrons so it gets 4 dots, and the Hydrogen has 1 valence electron, so it gets one dot. Together the carbon forms 4 single bonds with 4 hydrogens and together have 8 dots.

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).
