Importance of Maharashtra Board Class 12 Physics Chapter 15 Structure of Atoms and Nuclei

This chapter explains what an atom is made of. The atomic structure was developed after a series of experiments. One model proposed by a scientist was discarded by the other. Based on the discoveries made by scientists across the world, the modern structure of an atom was developed.


An atom comprises subatomic particles. Protons are the positively charged ones, and neutrons have no charge. These two subatomic particles remain inside the nucleus of an atom. The nucleus contains the entire mass of an atom. Outside the nucleus, the electrons spin in their respective orbits based on their energy levels.


The electrons are negatively charged and do not have significant mass. Their number is similar to that of the protons. This is why an atom is neutrally charged unless it loses or gains an electron.


The structure of the nucleus of an atom comprises protons and neutrons. These subatomic particles have different features and characteristics. To understand these concepts, refer to the Structure of Atoms and Nuclei Class 12 exercise solutions and notes compiled by the experts.

FAQs on Maharashtra Board Class 12 Solutions for Physics Chapter 15 Structure of Atoms and Nuclei- PDF

1. What is a nucleus of an atom?

The centre of an atom where protons and neutrons reside is called the nucleus of an atom. It contains almost the entire mass of an atom.

2. What is the difference between an atom and its nucleus?

An atom comprises protons, electrons, and neutrons. On the other hand, its nucleus only contains protons and neutrons. 

3. Can the nucleus of an atom vary?

The nucleus of an atom can vary in isotopes. The isotopes of an element vary in the number of neutrons present in its nucleus.

4. How do electrons get oriented in their shells?

The energy levels of the electrons decide the respective electronic shells that electrons will occupy.  

5. Name an atom that does not have neutrons.

Hydrogen atoms do not contain neutrons. Its isotopes deuterium and tritium contains neutrons.
