1. Who discovered Subatomic particle?James Chadwick discovered the neutron in 1932
2. What is the standard model particles?Includes quarks, leptons, and force-carrying bosons like photons and gluons
3. What is the composite particles?Protons and neutrons are made of smaller particles called quarks
4. What are subatomic particles?Subatomic particles are the tiniest pieces that make up everything around us, like tiny LEGO bricks inside atoms.
5. How do protons and neutrons stay together in the nucleus?The strong nuclear force, carried by gluons, pulls quarks inside protons and neutrons together and keeps the nucleus from flying apart.

Quark: A fundamental constituent of matter, forming protons and neutrons.
Lepton: A class of fundamental particles that includes electrons and neutrinos.
Photon: The fundamental particle of light and the carrier of the electromagnetic force.
Wave-Particle Duality: The concept that subatomic particles can exhibit properties of both waves and particles.
