Question

why do the neutrons and protons stick together in spite of being different charges?​

Answer 1

The explanation for why protons and neutrons stick together is known as "the strong force." The strong force is also known as the strong interaction, color force, or strong nuclear force.

Answer 2

Explanation:

Proton

Protons have a positive electric charge .

Neutron

Neutrons have no electric charge .

Neutrons and Protons are together called nucleons because they together constitute the nucleus .

In nucleus the Protons and Neutrons are stuck together because protons are charged particles but neutrons have no charge so the nucleus gets attractive in nature towards proton .

note :-

When two neutrons are brought together, the force between them is initially attractive, but around 0.5 fm it becomes repulsive. Neutrons neither attract or repel each other or other particles because they are electrically neutral i.e. they have no charge.
