•19 O Figure 39-28a shows the energy-level diagram for a fi-
nite, one-dimensional energy well that contains an electron. The
nonquantized region begins at E= 450.0 eV. Figure 39-28b gives
the absorption spectrum of the electron when it is in the ground
state-it can absorb at the indicated wavelengths: A=14.588 nm
and Ag = 4.8437 nm and for any wavelength less than A, = 2.9108

- Suppose the velocity of an electron in an atom is known to an accuracy of 2.0103 m/s (reasonably accurate compared with orbital velocities). What is the electron's minimum uncertainty in position, and how does this compare with the approximate 0.1-nm size of the atom?arrow_forwardHydrogen gas can only absorb EM radiation that has an energy corresponding to a transition in the atom, just as it can only emit these discrete energies. When a spectrum is taken of the solar corona, in which a broad range of EM wavelengths are passed through very hot hydrogen gas, the absorption spectrum shows all the features of the emission spectrum. But when such EM radiation passes through room-temperature hydrogen gas, only the Lyman series is absorbed. Explain the difference.arrow_forward(a) If one subshell of an atom has 9 electrons in it, what is the minimum value of l ?
