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.
This particle is the proton.
Proton
protons, no. of protons is equal to the atomic number of an element.
This particle is the proton, equal to the atomic number.
The subatomic particle that defines the element is the proton. The number of protons in the nucleus of an atom determines the element's atomic number, which differentiates one element from another on the periodic table.
The proton.
No, it is an element - a type of atom. The positive hydrogen ion, on the other hand, is usually identical with the proton, which is a subatomic particle.
A positively charged subatomic particle is a proton. Protons are found within the nucleus of an atom and carry a positive electrical charge.
my fellow questioner, a proon is an element _____ Actually a prune is a dried plum. A proton is a subatomic particle, it is not an element. However, the element hydrogen does turn into a proton when ionized. So it's close.
The number of protons defines the element.
A proton is a subatomic particle which is the same in whichever element it is found. A proton from a Xenon atom is no different to that from a Hydrogen atom or a Uranium atom.
Proton has a greater mass than the electron.
