Question

what happens to the distance between orbital of two consecutive shells with increasing n value

Answer 1

Orbital energies are measured relative to an electron at infinity (i.e. one which has been ionized), which corresponds to an energy of 0 eV. An electron which is lower in energy than this (i.e. bound to an atom) has a negative energy. The first six energy levels for hydrogen. As you can see, the energies converge to 0 as n, the principal quantum number, goes to infinity. In order to ionize an electron it must be given enough energy to promote it to the n = ∞ energy level. Therefore the higher the energy of the electron, the less energy is required to ionize it.

Answer 2

Answer:

Radius of Bohr's orbit is directly proportional to square of orbit number. Hence, distance between two consecutive orbit radius is r1(2n-1)
