It's the count of one of the subatomic particles in the nucleus, the proton, that is significant in this regard. For example, an atom is hydrogen if and only if it has one proton in its nucleus. It is neon if and only if it has ten protons in its nucleus.
You can define an element by the number of its protons and neutrons and its electron configuration.
Isotopes of one element differ only in neutron number and mass number
Atomic number does, it is the number of neutrons, protons, and electrons.
This particle is the proton.

.
The number of protons determines what is the element.
Electrons
Protons, electrons and neutrons
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
The number of protons is unique for every element.Varying the number of neutrons will give you an isotope of the same element.Varying the number of electrons will give you an ion of the same element.
The proton.
The number of protons defines the element.

An "element" is not a subatomic particle. Your question makes no sense and is therefore unanswerable.Another answer:Since an element is not a subatomic particle, the only answer can be a proton.
By looking at the atom.
Neutron
Silicon is a chemical element not a particle.
This particle is the proton.
Atom is a chemical element, not a particle.
