1) Shown below is the visible spectrum with its associated wavelengths. Indicate which of the wave images would best represent the waves associated with green light, purple light and orange light by typing in either green , purple , or orange in the appropriate text entry boxes. Answer: longest wavelength=orange; 2 nd longest wavelength=green; shortest wavelength=purple 2) At what speed (in meters/second) must an electron travel to have a wavelength equivalent to that of a photon of infrared light with energy 3.30 x 10 -20 J? 3) The image below depicts what type of orbital? 4) What is the maximum number of electrons in a subshell that can be described by the following quantum numbers? Answer: 10 n = 4 ℓ= 2 Which image would best represent one of the orbitals the electrons described by n=4 and ℓ= 2 would be in? answer: a D orbital 5) Choose the set of quantum numbers which would not be correct for any of the electrons in the ground state configuration of the element Na. answer: n=3, ℓ = 1, m = 0, m s = +1/2 n = 1, ℓ = 0, m = 0, m s = -1/2 n = 3, ℓ = 0, m = 0, m s = +1/2 n = 2, ℓ = 0, m = 0, m s = -1/2 n = 3, ℓ = 1, m = 0, m s = +1/2 n = 2, ℓ = 1, m = -1, m s = -1/2 Which of the following is an isotope of sodium, Na? answer: 22 Na 6) Enter the correct chemical symbol of the element that has this electron configuration. Make sure that you capitalize the first letter of the symbol! [Ne] 3s
