In Chapter 12 Atoms, we learnt that the positive and negative charges in every atom are densely packed and concentrated at the centre forming its nucleus. Now you might wonder if the nucleus has a structure, just as the atom does? If so, what are the constituents of the nucleus? How are these held together? In this chapter, these questions are answered. Also, we discuss various properties of the nucleus such as their mass, size and stability.

Frequently asked Questions on CBSE Class 12 Physics Notes Chapter 13: Nuclei
What is an ‘Isotope’?
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons.
What is ‘Radioactivity’?
Radioactivity is the act of emitting radiation spontaneously.
What is ‘Binding energy’?
The energy that holds a nucleus together is called the ‘Binding energy’. This is equal to the mass defect of the nucleus.
