The Wikipedia lists an estimate of 10 to the power 80 hydrogen atoms for the observable Universe. The total number of particles would be somewhere in that order, depending on what "particles" you are thinking of.
A colloid is not a subatomic particle.
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.
A negatively charged subatomic particle is an electron, or the antiproton.
The electron is the subatomic particle with a negative charge.
The electron is a subatomic particle that has a charge of -1.
The subatomic particle with a negative charge is called an electron.
Molecules are not subatomic particles.
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.
electronThe only radioactively stable subatomic particle is an electron.
Electrons are the subatomic particles that have a negative charge.
