2017-2 Honors Physical Science Periodic table review Multiple Choice Name: Period: Key Ma moy tightly Identify the letter of the choice that best completes the statement or answers the question. 1. Each row in the periodic table ends with a a. metal b. nonmetal B 2. In going from left to right in any given row in the periodic table, the size of atoms generally a. increases b. decreases metalloid d. noble gas c. stays the same d. changes randomly 3. Compared to the neutral atom from which it is derived, a negative ion is (-ion) (a) always larger b. always smaller c. larger in some cases and smaller in others d. the same size B 4. A metallic ion is its corresponding atom. (tion) a. larger than c. the same size as smaller than d. impossible to compare with 5. Bromine is a typical nonmetal . A bromide ion is a bromine atom. (a) larger than b. smaller than c. the same size as d. impossible to compare with (-ion) B 6. The most unreactive group of elements is the c. alkali metals d. transition elements a. halogens b. noble gases Matching Match each item with the correct statement below. a. alkali metal b. alkaline earth metal 2 c. halogen C Fluorine, bromine, or iodine A B A 8. An element found in Group 1 of the periodic table 9. In compounds, has an oxidation number of 2+ 10. Sodium or cesium 11. In compounds, has an oxidation number of 1- 12. An element found in Group 17 13. Magnesium or barium B A 14. 15. An element found in Group 2 B 16. Strontium, which is identified by the red color of fireworks 17. Astatine is the largest of this family In compounds, has an oxidation number of 1+ Short Answer 18 Question 18: What property did Mendeleev use to put elements in the same column on his periodic table? Answer: increasing atomic mass, similar props Question 19: What do elements in the same period of the periodic table have in common? Answer: Same #energy levels Question 20: What do elements in the same groups of the periodic table have in common? Answer: same #valence e Question 21: Tell if each of the following elements is a metal, metalloid, or nonmetal. Elements: Silicon, Sulfur, Bromine, Chromium, Arsenic, Aluminum, Calcium Answers: Metalloid, Nonmetal, Nonmetal, Metal, Metalloid, Metal, Metal Question 22: List 3 properties of metals. Answer: shiny, ductile, malleable, good conductors, solid, hard Question 23: List 3 properties of nonmetals. Answer: brittle, poor conductors, gas* Question 24: Complete the table below. Table: A table with columns for Element name, Group number, Metal, metalloid or nonmetal, Number of outer electrons, and Charge of ion. Elements: Sodium, Calcium, Aluminum, Nitrogen, Sulfur, Fluorine, Neon Data: The table is filled with appropriate data for each element. Question 25: Why do metals have less attraction for their outer electrons than nonmetals? Answer: Their outer energy level is far from filled so they'd rather give them up. Question 26: Tell which element atom is larger and why. Elements: Chlorine and Iodine Answer: Iodine has lower electron affinity, so it's larger. Question 27: Why are positive ions smaller than the atoms they were created from? Answer: Positive ions have fewer electrons so the nucleus can hold them more tightly. Question 28: Why are negative ions larger than the atoms they were created from? Answer: Negative ions have more electrons and the nucleus can't hold onto the extra electrons as tightly. Table: A table with columns for Name, Symbol, #Protons, #Neutrons, #Electrons, Atomic Number, and Atomic Mass. Elements: Carbon, Chlorine, Gold Data: The table is filled with appropriate data for each element.
