Chapter 5 PRACTICE TEST Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ____ 1. The idea of arranging the elements in the periodic table according to their chemical and physical properties is attributed to a. Mendeleev. c. Bohr. b. Moseley. d. Ramsay. ____ 2. Mendeleev is credited with developing the first successful a. periodic table. b. method for determining atomic number. c. test for radioactivity. d. use of X rays. ____ 3. Mendeleev did not always list elements in his periodic table in order of increasing atomic mass because he grouped together elements with similar a. properties. c. densities. b. atomic numbers. d. colors. ____ 4. Mendeleev predicted that the spaces in his periodic table represented a. isotopes. c. permanent gaps. b. radioactive elements. d. undiscovered elements. ____ 5. Mendeleevs table was called periodic because the properties of the elements a. showed no pattern. b. occurred at repeated intervals called periods. c. occurred at regular time intervals called periods. d. were identical. ____ 6. The person whose work led to a periodic table based on increasing atomic number was a. Moseley. c. Rutherford. b. Mendeleev. d. Cannizzaro. ____ 7. Moseleys work led to the realization that elements with similar properties occurred at regular intervals when the elements were arranged in order of increasing a. atomic mass. c. radioactivity. b. density. d. atomic number. ____ 8. Who used his experimental evidence to determine the order of the elements according to atomic number? a. Meyer c. Stas b. Ramsay d. Moseley ____ 9. The most useful source of general information about the elements for anyone associated with chemistry is a a. calculator. c. periodic table. b. table of metric equivalents. d. table of isotopes. ____ 10. Evidence gathered since Mendeleevs time indicates that a better arrangement than atomic mass for elements in the perio
