8. An ionic bond involves a. b. c. the unequal sharing of an electron pair an attraction between ions of opposite charge the sharing of a single pair of electrons 9. The primary reason that atoms form chemical bonds is so they can a. b. c. d. move into a more stable energy state change from one element to another become more electronegative become an isotope 10. An atom whose atomic number is 10 has how many electrons in its outermost energy level? b. 10 c. 8 d. 6 e. 3 11. Why do atoms give up, accept, or share electrons to form bonds? a. b. c. d. Atoms bond in order to become stable Atoms bond because they are polar Atoms bond to become radioactive isotopes Atoms bond because they are nonpolar 12. Which statement about the properties of water is true? ature easily, its molecules stick together and to nonpolar molecules, it dissolves Water changes temper nonpolar substances, and is denser as a solid than as a liquid. Water changes temperature slowly, its molecules do not stick together or to other polar substances, i dissolves other polar substances, and is less dense as a solid than as a liquid. Water changes temperature easily, its molecules stick together and stick to other polar molecules, it dissolves other polar substances, and is less dense as a solid than as a liquid. Water changes temperature slowly, its molecules stick together, and stick to other polar molecules, dissolves other polar substances, and is less dense as a solid than as a liquid. a. b. c. d. 13. Which is a correct statement regarding the difference between acids and bases? Bases release excess hydrogen ions (H') when they dissociate in water. Acids take up H' or release hydroxide ions (OH). Acids release excess hydrogen ions (H') when they dissociate in water. Bases take up H'or release hydroxide ions (OH). Acids are strong and bases are weak. Bases are strong and acids are weak. a. b. c. d. 14. Which is a correct statement regarding the pH scale? The pH scale ranges from O to 14. A pH value below 7 is basic and pH value above 7 is acidic. The pH scale ranges from 1 to 10. A pH value of 4 would indicate an acid, while a pH value of 9 woul a base. a. b. c. The pH scale ranges from 0 to 14. A pH value below 7 is acidic, while a pH value above 7 is basic. d. The pH scale ranges from O to 14. A ptH value of O is neutral, between 1 and 7 is basic, and from 8-1

Explanation / Answer

Answer 8 - An iconic bond involves (b) - The attraction between ions of opposite charge
