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 has a greater mass than the electron.
Proton
This particle is the proton, equal to the atomic number.
The number of protons determines what is the element.
protons, no. of protons is equal to the atomic number of an element.
The proton is a positively charged subatomic particle
The proton.
Protons, electrons and neutrons
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.
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.
