Question
I need the answer for thses questions by detials.
(c) (d) (e) 2.2 ev between 2 and 2.2 ev not enough information given. Answer questions 11 through 15 while using the energy-level diagram below for a hypothetical one-electron atom. 0 ev -1 ev Energy 4 eV 48. The ground-state energy of the electron is (a) 0 eV (b) -1 eV (c) -3 eV (d) -4 eV (e) -7 ev 49. The minimum energy required to ionize this atom from the ground state is (a) 1 eV (b) 3 eV (c)4 eV (d) 7 eV when in the ground state, the minimum excitation potential is (a) 1V (b) 3 V (c)4V (d)7 v 50, 51. The shortest possible wavelength in the atomic spectrum from this atom is about (b) 5.98 10-16 cm (e) 8.65 x 10-7 cm (c) 1.77 × 10-5cm (a) 2.8x 10.17 cm (d) 3.0 x 10-3 cm If an electron from outside the atom has 5 eV of energy, then a collision of this electron with this atom can cause (a) a transition in the atom from the -7 eV level to the -4 eV level. (b) a transition in the atom from the -7 eV level to the -1 eV level. (c) ionization of the atom from the -7 eV level. (d) all of the above. (e) none of the above. 52. -Explanation / Answer
48. -7 eV Since Energy gap is widest at the lowest level
49. 7 eV since ground state energy is -7 eV
50. 7 V
51. hc/Lambda = 7 eV, Calculating : Lambda = (6.6 x 10^-34 x 3 x 10^8) / (7 x 1.6 x 10^-19)
Answer 1.77 x 10^-5 cm
52. Transition of Energy difference less than or equal to 5 eV is possible,
Answer : (a)
