Neutrinos are uncharged particles and are so light that, for decades, most physicists assumed they were actually massless.

Neutron: An uncharged particle, very similar to the proton, which accounts for roughly half the particles in an atomic nucleus.

Dielectrophoresis is the motion of uncharged particles due to induced polarization from nonuniform electric fields.

He performed a series of experiments to verify this, these uncharged particles were eventually called "neutrons", and Chadwick is credited with this discovery.

The covariant form of the Dirac equation for an uncharged particle is:

The transfer of energy from an uncharged primary particle to charged secondary particles can also be described by using the mass energy-transfer coefficient.

Neutrons are a type of uncharged subatomic particle usually found in the nuclei of atoms.

Additionally it provides indirect measurement of the presence of non-interacting, uncharged particles such as neutrinos.

This device cannot, however, contain antimatter that consists of uncharged particles, for which atomic traps are used.

Then Chadwick devised an experiment that discovered a new, uncharged particle with roughly the same mass as the proton: the neutron.
