Neutron: They are neutral subatomic particles found in the center of the nucleus. They were discovered by James Chadwick in 1932. Protons and neutrons are therefore viewed as the same particle, but with different isospin quantum numbers; conventionally, the proton is isospin up, while the neutron is isospin down. The discoveries of electrons, protons and neutrons were made by J. J. Thomson, Ernest Rutherford and James Chadwick respectively. They were staggered over a period of 35 years. J. J. Thomson discovered the electron in 1897 through his studies of cathode rays, which he found were composed of negatively charged particles much smaller than atoms. Neutrons are particles that have no charge and are about the same mass as protons.

This element is number 20 on the Periodic Table of the Eleme Boron-11 is a chemical element that has five protons and six electrons. It is an uncommon element that is rarely found in the Earth's crust or atmosphere.
Protons and neutrons are in the center (nucleus) of the atom. You may want to mention that hydrogen is the only atom that usually has no neutrons. The nucleus of most hydrogen atoms is composed of just 1 proton. A small percentage of hydrogen atoms have 1 or even 2 neutrons. The neutron is a neutral particle present in the nucleus of an atom. Atoms of all the elements contain neutrons except hydrogen atom which does not contain any neutron. Neutron is a subatomic particle that is not found in hydrogen.

The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom.
