FAQs on Fundamental Particles Video Lecture - Crash Course for IIT JAM Chemistry

1. What are fundamental particles in chemistry?
Ans. Fundamental particles in chemistry are the smallest units of matter that cannot be further divided into simpler particles. They are the building blocks of atoms and are responsible for the various properties and behavior of matter.
2. How many types of fundamental particles are there in chemistry?
Ans. There are three types of fundamental particles in chemistry: protons, neutrons, and electrons. Protons carry a positive charge, neutrons have no charge, and electrons carry a negative charge.
3. What is the role of protons, neutrons, and electrons in an atom?
Ans. Protons are found in the nucleus of an atom and determine the atom's identity by defining its atomic number. Neutrons also reside in the nucleus and contribute to the atom's mass. Electrons orbit around the nucleus and are responsible for the chemical properties and reactivity of the atom.
4. Can fundamental particles be created or destroyed?
Ans. No, fundamental particles cannot be created or destroyed in a chemical reaction. The law of conservation of mass states that matter can neither be created nor destroyed, only transformed from one form to another. Therefore, the total number of protons, neutrons, and electrons remains constant throughout any chemical process.
5. How do fundamental particles interact with each other?
Ans. Fundamental particles interact with each other through various forces. Protons and electrons attract each other through electromagnetic forces, which hold the electrons in orbit around the nucleus. Protons and neutrons are bound together by the strong nuclear force, which overcomes the electromagnetic repulsion between protons. Electrons also interact with each other through the electromagnetic force, resulting in the formation of chemical bonds between atoms.
