Hi Everyone,I am wondering, if my homework isright...Please let me know if it is! Thanks! 1.Compare the properties of the blue and red ends of the visiblespectrum. The blue end: A. is higher in energy thanthe red end B. has a lower frequency than the red end C. has a longer wavelength than the red end D. all of the above are correct E. none of the above is correct 2.Emission of light from an atom occurs when an electron A. moves up one energy level B. climbs up two energy levels C. moves around the nucleus at an increased speed D. moves from a higher to a lower energy level E. gains a photon as it goes from a higher to alower energy level 3.Which of the following electron transitions corresponds to emissionof the longest wavelength light? A. from n = 3 to n = 2 B. from n = 1 to n = 5 C. from n = 4 to n = 2 D. from n = 1 to n = 2 E. from n = 5 to n = 1 4.Emission from an excited Hg atom emits at 254 nm. What is thefrequency of this light? A: 1.18e15 sec-1 B: 1.18e15 sec C: 1.18e6 sec-1 D:1.18e6 sec 5.Order the following elements in terms of increasing ionization energy:Ar, Cl, Na, S A: Na, S, Ar, Cl B: Cl, Ar, S, Na C: Ar, Cl, S, Na D: Na, S, Cl, Ar 6.Order the following elements in terms of decreasing electronaffinity (note that a decreasing electron affinity, refers to anincreasing tendency to want to capture an electron): Ar, Cl, Na,S A: Na, S, Ar, Cl B: Cl, Ar, S, Na C: Cl, S, Na, Ar D: Ar, Na, S,Cl 7.Order the following elements in terms of increasing atomic radii:Ar, Cl, Na, S A: Na, S, Ar, Cl B: Cl, Ar, S,Na C: Ar, Cl, S, Na D: Na, S, Cl, Ar 8.What is the correct electronic structure for Calcuim? A 1s2, 2s2 2p6 3s2 3p4 4s2 B:1s2 2s2 2p6 3s2 3p6 4s2 C:1s2 2s2 2p6 3s2 3p6 4d2 D:1s2 2p6 3d10 4f2 9.Order the following compounds in terms of increasingpolarity. CO,CCl4, NaCl, H2O A.
