$500 Question from H 3 What is the electron configuration for V+4?
$500 Answer from H 3 1 s 2, 2 p 6, 3 s 2, 3 p 6, 3 d 1
$100 Question from H 4 A B Compare the wavelength, frequency and energy of these two waves.
$100 Answer from H 4 Wave A has a longer wavelength and therefore a smaller frequency and less energy.
$200 Question from H 4 What is the energy of a wave with a frequency of 5. 5 x 1015 s -1?
$200 Answer from H 4 3. 4 x 10 -18 Js
$300 Question from H 4 What is the frequency of radiation whose wavelength is 6. 25 x 10 -5 cm?
$300 Answer from H 4 4. 80 x 1014 s-1
$400 Question from H 4 What is the energy of a wave with wavelength of 670. nm?
$400 Answer from H 4 2. 96 x 10 -19 J
$500 Question from H 4 Explain why different elements give off different colored light when heated.
$500 Answer from H 4 Each element has electrons in different sublevels. When you heat it, the electrons become excited. When they fall back to a lower energy state, they emit light. The color is related to the amount of energy between the sublevels and hence the amount of energy given off while “falling. ”
$100 Question from H 5 What is the difference between orbits and orbitals?
$100 Answer from H 5 An orbit is an exact, circular path that an electron follows whereas an orbital is a region in space where an electron may be found.
$200 Question from H 5 What is the maximum number of electrons in the third energy level? Explain.
$200 Answer from H 5 18 - 2 in the 3 s, 6 in the 3 p and 10 in the 3 d.
$300 Question from H 5 How do sublevels in the same energy level differ from each other?
$300 Answer from H 5 Their shapes are different. E. g. 3 s is spherical whereas 3 p is dumbell-shaped.
$400 Question from H 5 Using the ladder analogy, what do the rungs represent and why are the spaces between the rungs different sizes?
$400 Answer from H 5 The rungs are the energy levels and the spaces between them represent the amount of energy between the levels.
$500 Question from H 5 In your lab, you dropped marbles on a target. What did the marbles and the bull’s eye represent? Why did you drop them from different heights?
$500 Answer from H 5 The marble was the electron, the bull’s eye was the nucleus. They were dropped from different heights to simulate two different energy levels – the 1 s and the 2 s.
Final Jeopardy Explain how flame tests can best be used to identify an unknown ion in a solution of several ions.
Final Jeopardy Answer Every ion has a unique electron configuration and thus a unique set of electrons that can absorb and emit light. Compared to known flame colors, an unknown may be identified. However, in a mixture of ions, it may be necessary to use cobalt glass as well in order to filter out any ions which may give off yellow light.
