Passage VI

Consider an electron that is constrained to move along the x-axis. The probability of finding the electron at any given location, x, along the axis is obtained from a distribu­tion function, DF, which is related to the electron's energy. The greater the value of DF at a given x, the greater the probability of finding the electron at that x. Classical theory and quantum theory can be used to derive 2 forms of DF: a classical form and a quantum form.

Table 1 lists the electron energy corresponding to each of 4 DFs. Figure 1 shows the classical and quantum forms of each DF.

39. Each Quantum DF represents a unique physical state of the electron. The electron may make a transition from one state to another by either absorbing or emitting energy. Based on Table 1, if the electron were initially in the state represented by DF3 and then made a transition to the state represented by DF1 would the electron more likely absorb energy or emit energy, and how much? The electron would:

Answer and Explanation

Your Answer is

Correct Answer is C

Explanation

According to table 1, the electron energy of DF3 is 5, and the electron energy of DF1 is 1, so the energy reduction should be emit energy, which releases 5 -1=4 eV energy
