The ionization energy of hydrogen atom is 13.6 eV. Following Bohr's theory, the energy corresponding to a transition between 3rd and 4th orbit is
The total energy of electron in the ground state of hydrogen atom is -13.6 eV. The kinetic energy of an electron in the first excited state is
The mass number of a nucleus is
Solar is mainly caused due to
The volume occupied by an atom is greater than the volume of the nucleus by a factor of about
How does the binding energy per nucleon vary with the increase in the number of nucleons?
