Question

3. The Bohr model can be applied to any hydrogen-like ion (i.e. any ion with only one electron) This requires the following modification to the Rydberg equation, where Z is the atomic number 1 (RH)(Z)2 2 What is the ionization energy (in kJ/mol) of He* in its ground state? You must show all of your work to receive any credit Answer kJ/mol

Answer 1

SEBB The infinity level represents the point at which ionization of the elem occurs to form a positively charged to This, consider n=1 n a trenitton 2- adonic Neuchel Rt hy they, consta Ionization Enagy of het in its pound state - Bohr's equation cannot be applied to multicktron etans like Helion because it simply cannot account for esfer- mental data t e valid for Hydrogen like atoms, however, this being the reeren fire why the 2nd I & 9 Helium (or we can my T.E of Het is calculated As we know we cxt- - R - 1.097 x 107 ml 2-1 for Hydrogen I Putting values in equation N = 3x10 ms x 1.097 x 10 x 1²1 w = 3x1² 151 x 1.097 x 16²m 1 x to 2 3x10²mst x 1.997x67 In 3.291 X As we know, E ho ha 6.26 x 16 7 Jot E 6.368 X X 3.2.11 xl.
