  1. Chapter 6 review Turning Point

  2. Generally, how do atomic masses vary throughout the periodic table of the elements? • They increase from right to left and top to bottom. • They increase from left to right and bottom to top. • They increase from left to right and top to bottom. • They increase from right left and bottom to top. 0 of 35

  3. Which of the following ordered pairs of elements shows an increase in atomic number but a decrease in average atomic mass? • Ag to Pd • Ge to Sn • Cr to Mo • Te to I Response Grid

  4. Oxygen would have chemical properties most like • Selenium (Se) • Chromium (Cr) • Nitrogen (N) • Fluorine (F)

  5. Which group from the periodic table contains only metals? • Group 1 (1A) • Group 7 (7A) • Group 2 (2A) • Group 18 (8A) Response Grid

  6. Chlorine is commonly used to clean swimming pools. How is chlorine classified? • Nonmetal and halogen • Metal and noble gas • Metal and halogen • Nonmetal and noble gas Response Grid

  7. The ionization energy of an element indicates the energy it takes to remove an electron from the outermost energy level. As you move down a group in the periodic table, the ionization energy • decreases because the electron is farther away from the nucleus. • increases because the number of protons increases. • decreases because the number of neutrons increases. • increases because the size of the atom increases. Response Grid 10 Countdown

  8. Which of the following atoms has the largest atomic radius? • Barium (Ba) • Iodine (I) • Chlorine (Cl) • Magnesium (Mg) Response Grid 10 Countdown

  9. The electronegativity of an element indicates the relative ability of its atoms to attract electrons in a chemical bond. As you move across a period(to the right) in the periodic table, the atomic number • A increases and the electronegativity increases. • B increases and the electronegativity decreases. • C decreases and the electronegativity increases. • D decreases and the electronegativity decreases. Response Grid 10 Countdown

  10. Which of the following elements is not a metalloid? • Boron (B) • Gallium (Ga) • Arsenic (As) • Polonium (Po) Response Grid 10 Countdown

  11. The periodic table is useful because it is organized to show many patterns and trends. Which property shows an increase moving from the bottom of Group 1 diagonally to the top of Group 17? • Reactivity • Atomic radius • Atomic mass • electronegativity Response Grid 10 Countdown

  12. In which group are the alkali metals found? • 1A • 7A • 8A • 3A Response Grid 10 Countdown

  13. Which group of elements has two electrons available for bonding? • Group 1A • Group 16 (6A) • Ground 2A • Group 17 (7A) Response Grid 10 Countdown

  14. Sodium reacts with bromine to form sodium bromide. How many valence electrons does each sodium atom have available for bonding? • 1 • 7 • 4 • 8 Response Grid 10 Countdown

  15. Which of the following atoms has four valence electrons? • Magnesium (Mg) • Selenium (Se) • Silicon (Si) • Argon (Ar) Response Grid 10 Countdown

  16. How does the nucleus compare to the entire atom? • It is slightly smaller than the atom. • It is the only part of the atom that has a charge. • It contains most of the atom’s mass. • It contains all of the atom’s mass. Response Grid 10 Countdown
