Quiz Standard 1 Answer Key Teacher Name: Quiz Generated On: 04-28-2016 1) Identify the number of neutrons in one atom of sulfur with an isotopic mass number of 34 amu. A) 16 B) 18 C) 32 D) 34 None of the E) above Explanation: One atom of sulfur with an isotopic mass number of 34 has neutrons. 34 (total) - 16 (protons) 18 = 18 (neutrons). 2) Which is true of ionic compounds? They are good conductors as A) solids. They are made by sharing B) electrons. They are made of metals and C) nonmetals. They are electrically neutral when dissolved in D) a solution. None of the E) above Explanation: They are made of metals and nonmetals is true of compounds. They usually form between elements on opposite sides of the periodic table. Ionic compounds are only good conductors when molten or dissolved. When dissolved, they form ions, charged particles. Ionic compounds transfer electrons. 3) Which is true of all covalent compounds?
