1 Chapter 6 review Turning Point

2 Generally, how do atomic masses vary throughout the periodic table of the elements? 1.They increase from right to left and top to bottom. 2.They increase from left to right and bottom to top. 3.They increase from left to right and top to bottom. 4.They increase from right left and bottom to top.

3 Which of the following ordered pairs of elements shows an increase in atomic number but a decrease in average atomic mass? 1.Ag to Pd 2.Ge to Sn 3.Cr to Mo 4.Te to I

4 Oxygen would have chemical properties most like 1.Selenium (Se) 2.Chromium (Cr) 3.Nitrogen (N) 4.Fluorine (F)

5 Which group from the periodic table contains only metals? 1.Group 1 (1A) 2.Group 7 (7A) 3.Group 2 (2A) 4.Group 18 (8A)

6 Chlorine is commonly used to clean swimming pools. How is chlorine classified? 1.Nonmetal and halogen 2.Metal and noble gas 3.Metal and halogen 4.Nonmetal and noble gas

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 Countdown 10 Response Grid 1.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.

8 Which of the following atoms has the largest atomic radius? Countdown 10 Response Grid 1.Barium (Ba) 2.Iodine (I) 3.Chlorine (Cl) 4.Magnesium (Mg)

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 Countdown 10 Response Grid A increases and the electronegativity increases. B increases and the electronegativity decreases. C decreases and the electronegativity increases. D decreases and the electronegativity decreases.

10 Which of the following elements is not a metalloid? Countdown 10 Response Grid 1.Boron (B) 2.Gallium (Ga) 3.Arsenic (As) 4.Polonium (Po)

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? Countdown 10 Response Grid 1.Reactivity 2.Atomic radius 3.Atomic mass 4.electronegativity

12 In which group are the alkali metals found? Countdown 10 Response Grid 1.1A 2.7A 3.8A 4.3A

13 Which group of elements has two electrons available for bonding? Countdown 10 Response Grid 1.Group 1A 2.Group 16 (6A) 3.Ground 2A 4.Group 17 (7A)

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

15 Which of the following atoms has four valence electrons? Countdown 10 Response Grid 1.Magnesium (Mg) 2.Selenium (Se) 3.Silicon (Si) 4.Argon (Ar)

16 How does the nucleus compare to the entire atom? Countdown 10 Response Grid 1.It is slightly smaller than the atom. 2.It is the only part of the atom that has a charge. 3.It contains most of the atom’s mass. 4.It contains all of the atom’s mass.
