    If you would like to become a nuclear physicist, what you would like to know about the nucleus first?

    A. structure of the nucleus Every atom consists of a dense positive central core of mass, known as nucleus. Its size is much smaller compared to the size of the atom, nut nonetheless it contains almost all of the mass of the atom. The nucleus is made of only neutrons and protons. — These are…
