Which statement(s) related to the energy levels of electrons is/are true? Choose all that apply.
Select one or more:
a. Electrons can sometimes be found between the energy levels.
b. An electron in an atom can occupy any of the atom's energy levels.
c. The wavelengths of the photons emitted or absorbed are unique to a specific element.
d. Electrons within an atom require the absorption or emission of a photon of any wavelength to change energy levels.
e. The energy level farthest from the nucleus is the first excited state.
Homework Answers
Option a is not correct as we know that electron can not exist between the states. they only can be found in the allowed energy states.
Option b is correct. An electron can occupy any allowed state. However all transitions are not allowed.
Option c is correct. The wavelength of photon emmited or absorbed are unique. Energy of emitted or absorbed photon is equal to the energy difference between the two states.
First excited energy level means the energy level just above the ground state. It is not necessarily the farthest energy level from the Nucleus. So option d is incorrect.
Option d is incorrect reson is same as in c.

How does the energy possessed by an emitted photon compare to the difference in energy levels that gave rise to the emission of the photon? When a tube containing hydrogen atoms is energized by pass- ing several thousand volts of electricity into the tube, the hy- drogen emits light that, when passed through a prism, resolves into the "bright line" spectrum shown in Fig. 11.10. Why do hydrogen atoms emit bright lines of specific wavelengths...

Select true or false for each statement below. True False Electron states are described by orbits, which indicate exactly where an electron is located in an atom. True False The energy levels of all atoms except hydrogen are quantized. True False Electrons move in elliptical orbits around the nucleus of an atom. True False Atoms can gain energy by absorbing a photon. True False When atoms are in an excited state, they can release this energy by emitting light.

A certain type of atom
(not hydrogen) has three energy levels numbered 1, 2, and
3, as shown in the upper illustration. There are three possible
transitions between these levels that lead to emission of a photon:
3 ® 1, 3 ® 2, and 2 ® 1.
The lower illustration shows the emission spectrum from a gas of
these atoms. There are three emission lines, A, B, and C.
