What is the name of this element

Carbon

Explanation:

This elelemnt is carbon because it has 6 protons. The number of electrons determines the type of element. Only carbon can have 6 protons. The mass number is 13. 6 protons + 7 neutrons = mass of 13. This is an isotope of carbon. This isotope is called carbon-13.

protons = positive charge (in the nucleus) tells what the element is

neutrons = neutral charge (in the nucleus)

electrons = negative charge (orbits the nucleus)

mitosis

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).
