An electron on a hydrogen atom emits light with a wavelength of 1090 nm when tailing to the n = 3 level. From which level did it fall? Indicate which of the following sets of quantum number, (n, l, m_1, m_s) are correct. If incorrect, indicate why. a) (1, 0, 1, 1/2) b) (3, 2, 0, -1/2) c) (2, 4, -1, 1/2) d) (0, 0, 0, 1/2) e) (5, 3, -1, 2) Give the abbreviated electron configuration for each of the following: a) Se b) Mo c) Cr^3+ d)Pt c) I Using orbital diagrams to prove your answer, determine the number of unpaired electrons in each of the following: a) Co^2+ b) Ag c) S Arrange the following in order of decreasing electronegativity (e.g. x>y>z): Mo, Ge, Ba, S, Si, Sr Draw the Lewis structure (including any resonance forms), stage the geometry, indicate the polarity and determine the hybridization of the central atom in each of the following: a) SiH_3Br b) BeFCI c) NO_3^-1 d) SeF_6 Use the concept of formal change to prove which is the correct Lewis structure for SOCI_2.
