What is a neutrally charged subatomic particle?

Answer 1

You're most likely asking about the neutron.

However, there are others, like neutrinos (all three types), pions, kaons, eta mesons, as well as the sigma, the lambda, and the xi particles

Answer 2

A neutrally charged subatomic particle is a neutron. Neutrons have no electric charge and are found in the nucleus of atoms alongside protons. They contribute to the mass of an atom without affecting its overall charge.

Answer 3

Neutrons, neutrinos, anti-neutrinos, gravitons, W bosons, and Z bosons, among others, all have neutral charges.
