It is the electrons that are responsible for the chemical bavavior of atoms, and which identify the various chemical elements.

How are the chemical properties of a solid, liquid, gas, and plasma determined?

The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons. The configuration of these electrons follows from the principles of quantum mechanics. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. In the periodic table, the elements are listed in order of increasing atomic number Z.
