Bohr was not the discoverer of a particle.
A colloid is not a subatomic particle.
A quark is a kind of subatomic particle, and 3 quarks makes up another subatomic particle (a baryon). A quark and an anti-quark make up another kind of sub-atomic particle, (a meson).
James Chadwick discovered the neutron, a subatomic particle that is found in the nucleus of an atom. He made this discovery in 1932, building upon the work of previous scientists in the field of atomic theory.
The lightest subatomic particle is the electron.
The subatomic particle that has no charge is a neutron.
This particle is the electron.
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.
