1.	According to Bohr's theory, the energy of an electron in the nth energy level of hydrogen like species is given by: En=−21.76×10−19n2(Z2) J Calculate the longest wavelength of light that will be needed to completely remove an electron from the third Bohr orbit of He+ ion.
Answer» According to Bohr's theory, the energy of an electron in the $n^{t h}$ energy level of hydrogen like species is given by: $E_{n} = \frac{- 21.76 \times 10^{- 19}}{n^{2}} (Z^{2}) J$ Calculate the longest wavelength of light that will be needed to completely remove an electron from the third Bohr orbit of $H e^{+}$ ion.
