The Neutron
Neutron has a mass of approximately 1 atomic mass unit (u) and carries no electric charge. It is a subatomic particle found in the nucleus of an atom alongside protons.
electron
The term nucleon is applied to any particle that makes up an atomic nucleus. That means it can be applied to either a proton or a neutron (but only when we are talking about them as the components of an atomic nucleus). The nucleon with the positive charge is the proton. You'll recall that the neutron is a neutral particle; it has no charge.
Electron
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
Both one proton and one neutron each has a relative mass of 1 a.m.u.
The neutron is a subatomic particle that has mass nearly equal to that of a proton but carries no electrical charge.

No such particle exists. All particles with charge also have mass -- no exceptions. Every particle with zero mass also has zero charge -- no exceptions.
A subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen
