- Question 01:
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?
- Question 02:
Which element will the most likely ion of sulfur, be isoelectronic with?
- Question 03:
The PES spectrum for magnesium atoms will show how many peaks, and in what ratio of heights?
- Question 04:
How many occupied outer shell orbitals does an arsenic (atomic number 33) atom possess?
- Question 05:
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?
- Question 06:
The electronic configuration of Fe3+ is?
- Questions 07-09:
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.
What is the best explanation for each pink peak, being to the left of the corresponding blue peak in each case?
- Question 08:
Which of pink peaks represents an electron that will be removed during the following process?
Ne(g) → Ne+(g) + e-
- Question 09:
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?
- Question 10:
Which electron transition would release the greatest amount of energy?
