An element has an atomic number of 79. the number of protons and elections in a neutral atom of the element
a. 197 protons and 79 electrons
b. 79 protons and 0 electrons
c. 79 protons and 79 electrons
d. 79 protons and 197 electrons

the answer is C.

Explanation:

atomic number = number of protons

electron= protons (in a neutral atom.)

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).
