The number of protons in an atom determines which element it is (i.e Silver-47 protons vs. Gold-79 protons)
This particle is the proton.
These particles are the protons.
This particle is the proton.
The number of protons determines what is the element.
The number of protons is determining the element
In the chemical reactivity of atoms electrons are involved.
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.
The number of protons tells you which chemical element the atom is. The number of neutrons determines the isotope of the element.
The number of protons defines the element.
Proton
The electron.
Neutron
Silicon is a chemical element not a particle.
Atom is a chemical element, not a particle.
