Question

What is the charge on neutrons?

Answer 1

Atom is the tiny particle consisting of subatomic particles like electrons, protons and neutrons. Electrons are negatively charged particles that are present outside the nucleus, and the subatomic particles neutrons and protons are present inside the nucleus, but the neutrons are no charged species.

Complete answer:
Molecules are the combination of one or more atoms. Atom is a tiny particle and is not visible to the human eye, it contains the subatomic particles. The most important subatomic particles are electrons, protons and neutrons.
Nucleus is the heavy portion that is present in the center of the atom, it is positively charged and attracts the negatively charged particles like electrons.
Electrons are negatively charged subatomic particles that are present outside the nucleus. Protons are positively charged subatomic particles that are present inside the nucleus.
Neutrons are no charged subatomic particles that are also present inside the nucleus, but as the nucleus contains protons and neutrons it becomes positively charged. Neutrons and protons number gives the mass number of atoms. Neutrons have the mass nearly equal to the proton, but very greater than the mass of electrons.
The charge of neutrons is zero thus, the neutrons are no charged particles, and the mass of the neutrons is $1.67 \times {10^{ - 27}}kg$ .

Note :
The sub-atomic particles with zero charge are neutrons, while protons are positively charged subatomic particles and electrons are negatively charged subatomic particles. Neutrons were discovered by James Chadwick in $1932$ and named as neutrons by him after the discovery of no charged particles.
