A single electron orbits around a stationary nucleus of charge $$+Ze$$, where $$Z$$ is a constant and $$e$$ is the magnitude of the electronic charge. It required $$47.2\ eV$$ to excite the electron from the second Bohr orbit to the third Bohr orbit. Find the value of $$Z$$.

The total energy of in the electron in the hydrogen atom in the ground state is $$-13.6\ eV$$. Which of the following is its kinetic energy in the first exited state?

If the attractive potential between electron and proton were given by $$V(r) = V_{0}ln \left (\dfrac {r}{r_{0}}\right )$$ (where $$V_{0}, r_{0}$$ are constants), the radius $$r_{n}$$ of the $$nth$$ Bohr orbit in Hydrogen atom would be proportional to

If element with principal quantum number $$n > 4$$ were not allowed in nature, the number of possible elements would be
