Question

explain the characteristics of nucleus​

Answer 1

Answer:

(i) Nucleus is a small, heavy, positively charged portion of the atom and located at the centre of the atom. (ii) All the positive charge of atom (i.e. protons) are present in nucleus. (iii) Nucleus contains neutrons and protons, and hence these particles collectively are also referred to as nucleons.

Answer 2

Explanation:

Nuclear force is the force that binds the neutrons and protons in a nucleus together.

The following are the few characteristics of nuclear force : -

• 1. It is attractive in nature but with a repulsive core. That is the reason that the nucleus is held together without collapsing in itself
• 2. Nuclear force is identical for all nucleons.
• 3. At a distance less than 0.7 Fermi, this force becomes repulsive. It is one of the most interesting properties of nuclear force, as this repulsive component of the force is what decides the size of the nucleus.
