It determines its chemical properties
The subatomic particle that determines an atom's chemical properties is the electron. Electrons are involved in chemical bonding between atoms, which determines the reactivity and behavior of elements. The number and arrangement of electrons in an atom's electron cloud dictate how it interacts with other atoms.
Electrons are the subatomic particles found outside the center of the atom and are responsible for the chemical properties of the atom. Their arrangement in the electron cloud determines the reactivity, bonding, and other chemical behavior of the atom.
The number of electrons is very important.
The electron shell is the source of an element's chemical properties and the moderator of chemical reactions; the electron shell depends on the protons that constitute the atom

In the chemical reactivity of atoms electrons are involved.
The number of protons tells you which chemical element the atom is. The number of neutrons determines the isotope of the element.
Protons, neutrons, and electrons are the subatomic particles used to classify the properties of an element. The number of protons determines the element's atomic number and defines its chemical properties. Neutrons help determine the stability of an atom, while electrons influence its reactivity and bonding behavior.
