AP MCQ 01EFGH PART 1

If a photon has frequency = 2.00 x 10¹⁴ s^-1 and the speed of light = 3.00 x 10⁸ ms^-1, then what is its wavelength?

Which element will the most likely ion of sulfur, be isoelectronic with?

The PES spectrum for magnesium atoms will show how many peaks, and in what ratio of heights?

How many occupied outer shell orbitals does an arsenic (atomic number 33) atom possess?

It is found that a mixture of the elements with atomic numbers 5 through 9 inclusive, produce a PES plot where the peaks representing the 1s sub-shell of each element, all have different heights. What is the best explanation for this observation?

The electronic configuration of Fe³⁺ is?

Questions 7-9 concern the simulated PES plots of oxygen and neon that are superimposed upon one another in the diagram below. Pink peaks represent neon, blue peaks represent oxygen.

Question 07:

What is the best explanation for each pink peak, being to the left of the corresponding blue peak in each case?

Which of pink peaks represents an electron that will be removed during the following process?

Ne_(g) → Ne⁺_(g) + e^-

If a third set of peaks were to be superimposed on to the same plot, this time for the PES spectrum for sodium, what would one expect to observe?

Which electron transition would release the greatest amount of energy?
