Unformatted text preview: wilson (tw8656) H07 : Polarity mccord (50960) 1 This print-out should have 14 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points In general, electronegativity tends to decrease 1. from top to bottom and from left to right on the periodic table. 2. from bottom to top and from left to right on the periodic table. 3. in no regular trend. 4. from top to bottom and from right to left on the periodic table. correct 5. from bottom to top and from right to left on the periodic table. Explanation: Electronegativity generally increases from left to right and from bottom to top of the Periodic Table. 002 10.0 points Rank the following in terms of increasing elec- tronegativity. 1. Na, Mg, N, O, F correct 2. F, O, N, Mg, Na 3. F, O, N, Na, Mg 4. Na, N, O, Mg, F 5. F, Mg, Na, O, N Explanation: Electronegativity is the measure of an ele- ments tendency to attract electrons to itself. Electronegativity is greatest for elements at the top right of the periodic table (EN of F = 4.0) and least for elements at the lower left of the periodic table. 003 10.0 points Calcium is electropositive compared to fluo- rine. 1. False 2. True correct Explanation: Fluorine is the most electronegative ele- ment....
