1. All of these compounds will have a completed octet on each atom except hydrogen. What observations can you make about the number of valence electrons in the Lewis structure and the number of bonds or multiple bonds present.

beta decay is the answer

the product of the pressure and volume is also constant

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).
