Want this question answered?
Of the hundreds of subatomic particles, many have an electric charge. The best-know particle with a positive charge is the proton. Subatomic particles are considered only protons, neutrons, electrons. The other particles form the large group of elementary particles (which includes also p, n and e).
The only subatomic particles that exist in an atom are protons, neutrons, and electrons.
An atom of helium with a mass of 4 atomic mass units (amu) would typically contain 4 subatomic particles. Two of these particles would be protons, two would be neutrons, and two would be electrons.
There are many subatomic particles with negative charge, but the first negatively charged particle that anyone learns about is the electron. It is only invisible in the sense that humans can not see it because it is so small. It is a perfectly normal subatomic particle and certainly the most common negatively charged particle in the universe.

Xenon 132 has 54 protons and 54 electrons and 78 neutrons.
2 protons, 2 electrons and 2 neutrons
There are many particles that contribute to the make up an atom. An electron is the subatomic particle that has a negative charge. The muon and tau particle also are negatively charged.
The particles outside of an atom are called electrons :D

Atoms can have anywhere from 1 to somewhere around 260-290 subatomic particles. The protons and neutrons are located in a clump in the center of the atom, surrounded by rapidly revolving electrons

The atom of a chemical element contain protons, neutrons and electrons; the number is specific for each isotope.
There are many neutral particles which are made up of charged quarks e.g. the neutron) but the only fundamental neutral particles are neutrinos, photons, Z bosons, and gluons.
