Q)
(chatquestion)...9. An electron is in an excited state in a
hydrogen like atom. It has a total energy of
-3.4 eV. The kinetic energy of the electron is
E and its de Broglie wavelength is 2. Then
a) E=6.8 eV, 1 = 6.6×10¬10
b) E= 3.4 eV, 2 = 6.6 ×10-10
c) E=3.4 eV,
= 6.6 × 10-11
d) E=6.8 eV, 1 = 6.6×10¬11
