Incorrect statement about nucleus – Rankers Physics

Nucleus: Practice Problem & Solution

Choose the incorrect statement among the following.
Nuclear density is independent of A and it is of the order of \( 10^{17}\text{ kg/m}^3 \)
Neutrons and protons are bound in a nucleus by the short-range strong nuclear force.
Nuclides with same atomic number Z, but different neutron number N are called isotones
In nuclear reaction, the total number of neutrons and protons is the same on either side of a reaction

Solution Explained:

To solve this problem, we apply the core principles of Nucleus. Understanding the underlying formula is key to arriving at the correct answer below:

Nuclides with the same atomic number \( Z \) but different neutron numbers \( N \) are called isotopes, not isotones. Thus, option C is incorrect.
