The following values are the only allowable energy levels of a hypothetical one-electron atom: E = -2.0 * 10-19 Ex = -7.0 * 10-19 eBook E4--11.0*10-13 Print References E, --15.0 x 10-19 E, --17.0 10-19 E; --20.0 x 10-19, () Ir the electron were in the level, what would be the highest frequency (and minimum wavelength) of radiation that could be emitted? Frequency- 10 Wavelength - * 10m (6) What is the lonization energy (in kJ/mol) of the atom in its ground state? x 10(select) 9 kJ/mol (c) If the electron were in the level, what would be the shortest wavelength (in nm) of radiation that could be absorbed without causing lonization?

formula used E nho Where n=4, h = 6.626x10-347 sec Es +.0 x10ml95 11.0XIn'9J = 4 x 6.626x10 34 7 sec XV Voll0x19-19. = 14.15x10!4 sec 4x6.626 X10-345 sec b) we know o=e Sp da 3.0x10% mysec 9.23. xiom 4.15x1014 secs we know E, = -20.0x1095 Em = 0 as on ionisation electron jumps from group State to (o) state so QE = E. -E, → 0-(-20x10495) DE = 20x10495 /atom 1 1 atan have ionisation energy = 20x10, so 6.023x1013 atum have conisation energy = 20x10x6-023 x16' I = 1204-64103 J/mole = (120406 kJ/mol -12°046 X 10^KJ/mof c) As above d= 7.23x10 m for n=4 10-9m - inm so . 7.23 x 15tm - 7:23x10 m G 109m = +23 nm
