All are remarkable but in the atom I consider that the most important is the proton.
Basically, atoms are made up of subatomic particles. Subatomic, sub- meaning smaller that, so subatomic particles means "a particle smaller than an atom". So It means that it is a particle within the atom.
The proton.
A colloid is not a subatomic particle.
Answer Electrons
The lightest subatomic particle is the electron.
The subatomic particle that has no charge is a neutron.
The subatomic particle with a negative charge is the electron.
The electron is a subatomic particle that has a charge of -1.
A negatively charged subatomic particle is an electron, or the antiproton.
The electron is the subatomic particle with a negative charge.
The subatomic particle with a negative charge is called an electron.
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.
