Why can an element be identified by its properties?

Determining Chemical Properties using the Periodic Table. Chemical properties of each element are determined by the element's electronic configuration, and particularly by its outermost valence electrons. ... In addition, the total number of electron shells an atom determines which period it belongs to.

Explanation:

hope it helps you :)

Each element can be identified by using their own specific properties. Since each element has a different number of protons and neutrons, these individual elements have their own atomic number and mass number properties.

c is the answer because when something is left after something evaporates that shows the chemical change.

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).
