60. Place the following in order of decreasing metallic character: As K P a) P > As > K b) As > P> K c) K > P > As d) As > K > P e) K > As > P 61. Which has the largest electronegativity? B) Sn C) Sb D) Te E) I 62. The electronegativity for carbon and sulfur is 2.5. Therefore, the compound CS2 would be expected to A) Br a) be ionic with C as the anion. b) be ionic with C as the cation. 63. Atoms having greatly different electronegativities would be expected to form a. no bonds b. polar covalent bonds c. nonpolar covalent bonds c) have nonpolar covalent bonds between C and S. d) have polar covalent bonds between C and S. A) 14 B) 16 64. Complete the Lewis structure for HC10₂ from the skeletal template below. How many nonbonding electrons are in the molecule? H O CI O C) 18 D) 20 E) 26 65. The molecular shape of the AsH3 molecule is (A) octahedral. (C) trigonal pyramidal. d. ionic bonds e. covalent bonds (B) (D) trigonal planar. tetrahedral. 66. According to the kinetic molecular theory, the pressure of a gas in a container will decrease if the A) number of collisions with the container wall increases. B) container is separated in two by a steel barrier. C) number of moles of the gas increases. D) volume of the container decreases. E) temperature of the gas decreases. 60.
