Unformatted text preview: kramer (jrk2286) Homework 2 sutcliffe (90830) 1 This print-out should have 30 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. This HW covers the material on Exam 2. 001 10.0 points Which of the following elements would be ex- pected to have the highest electronegativity? 1. As 2. Ge 3. P 4. Li 5. Al 002 10.0 points All of the following can have the ground-state electron configuration [Xe] 4 f 14 5 d 10 except 1. Pb 4+ 2. Tl + 3. Hg 2+ 4. Bi 5+ 5. Au + 003 10.0 points Arrange the following ions in order of increas- ing radius: K + , Li + , Be 2+ , Na + . 1. Li + < Na + < K + < Be 2+ 2. Be 2+ < Li + < Na + < K + 3. K + < Be 2+ < Li + < Na + 4. Na + < K + < Be 2+ < Li + 004 10.0 points F- is bigger than F because 1. F- has one more electron so there is less effective shielding of the nuclear charge. 2. F- has one less electron so there is less effective shielding of the nuclear charge. 3. F- has one more electron which causes less electron repulsions in the outer orbitals, thus expanding the electron cloud. 4. F- has one less electron so there is more effective shielding of the nuclear charge. 5. F- has one more electron which causes greater electron repulsions in the outer or- bitals, thus expanding the electron cloud. 005 10.0 points If the following crystallize in the same type of structure, which has the lowest lattice energy? 1. NaI 2. LiCl 3. KCl 4. KI 5. NaCl 006 10.0 points Which of the following contains only covalent bonding and no ionic bonding? 1. CCl 4 2. Na 2 SO 4 3. NaOH 4. Ca(NO 3 ) 2 5. NaCl 007 10.0 points Use electron-dot notation to demonstrate the formation of an ionic compound involving the elements Al and S. kramer (jrk2286) Homework 2 sutcliffe (90830) 2 1. Al + S + S + S- Al 3+ + S- + S- + S-- Al 2 S 3 2. Al + Al + Al + S- Al + + Al + + Al + + S 3-- Al 3 S 3....
