Consider a neutrally charged atom that has an atomic mass number of 80, which includes 35 neutrons. how many electrons does this atom have?

45 electrons.

Explanation:

mass number = 80

no. of neutrons = 35

Given that it is a neutrally charged atom,

no. of electrons = mass no. - no. of neutrons

                          =    80 - 35

                          =      45 electrons.

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).
