Answer 1

Nuclear Part - All the positive charge and most of the mass of an atom is concentrated in a very small region at the center of the atom called Nucleus. All protons and neutrons are present inside the nucleus. Protons and neutrons are collectively called as nucleons.

Extra Nuclear Part -The space of the atom outside the nucleus is called extra nuclear part. In this part electrons are revolving continuously around the nucleus at very high speed in a closed circular path called orbits.

Electrostatic Force -This force is acting between electrons and nucleus which is balanced by centrifugal force acting on the Electron.
