Webb17 mars 2024 · The Bohr Theory gives accurate values for the energy levels in hydrogen-like atoms, but it has been improved upon in several respects. Hence, the radius of 2nd and 3rd Bohr orbit in a hydrogen atom is 2.116 and 4.761 Angstrom. Note: There are certain limitations to Bohr’s theory. WebbSince negative of Ionization energy is the energy of first stationary state, for He+, the energy of 1st level is -19.6 x 10^-18 J atom-1. The energy of an electron in 1st level for He+can be written as: E1 = -K (Z^2 /n^2 ) = - K x (2^2/1^2 ) = -4K Hence K = -19.6 x 10^-18 / 4 = 4.9 x 10^-18 J atom-1
