A)   an atom has the characteristics of the element B)   the nucleus of an atom is make up of protons and neutrons C)   the proton has a positive charge and the neutrons has no charge D)   electrons are found in shells around the nucleus E)   a neutral atom has more neutrons than protons and electrons Answer: E Reference: 2.1 Level of Difficulty: Medium 3) The smallest unit of matter that retains the properties and characteristics of an element is the: A)   atom. B)   molecule. C)    proton.  http://getbooksolutions.com  D)   nucleus. E)   electron. Answer: A Reference: 2.1 Level of Difficulty: Easy 30  http://getbooksolutions.com  4) Which of the following carry a negative charge? A)    protons only B)   neutrons only C)   electrons only D)    both protons and electrons E)    both electrons and neutrons Answer: C Reference: 2.1 Level of Difficulty: Easy 5) An atom of one element is distinguished from an atom of another element by the number of: A)   neutrons in the nucleus. B)   electrons in the nucleus. C)    protons in the nucleus. D)   electrons orbiting the nucleus. E)   electrons it can lose when bonding. Answer: C Reference: 2.1 Level of Difficulty: Medium 6) Isotopes are A)   charged atoms that gained or lost electrons. B)   atoms of different elements that have the same atomic mass. C)   able to release radiation if their nuclei are unstable. D)   atoms with unpaired electrons in their outermost shells. E)   atoms with the same numbers of neutrons but different numbers of protons. Answer: C Reference: 2.1 Level of Difficulty: Medium 7) What determines the atom ’s chemical properties?  A)    protons B)   neutrons 31  http://getbooksolutions.com  C)   electrons D)   the nucleus E)   all of the above Answer: C Reference: 2.1 Level of Difficulty: Medium 8) Which of the following is an ion and why? A)   O 2 -  because it contains an unpaired electron in its outer shell. B)    Na +  because it has lost an electron. C)   Co-60 because it is radioactive. D)   H 2  because it is sharing electrons. E)   H-3 because it has two extra neutrons. Answer: B Reference: 2.1 Level of Difficulty: Medium 9)   A manufacturing company uses a very effective solvent that is composed of groups of atoms with unpaired electrons in their outermost electron shells. Which of the following is true? A)   The solvent ’s atoms are isotopes with unstable nuclei that releases radioactivity.  B)   Workers using the solvent have decreased risk of cataracts, atherosclerosis, or cancers. C)   Inclusion of antioxidants in workers ’ diets may help protect th em from effects of the solvent. D)   The solvent is electrically neutral and therefore poses no risks to workers. E)   The unpaired electrons in the solvent atoms will stabilize molecules in the workers ’ bodies.  Answer: C Reference: 2.1 Level of Difficulty: Hard 10) Which of the following is true of the chemical formula, H 2 O 2 ? A)   The formula represents four atoms sharing electrons. B)   The formula represents an element. C)   The formula represents two ions of hydrogen and two ions of oxygen. D)   The formula indicates the presence of two molecules each of hydrogen and oxygen. E)   The formula indicates the transfer of electrons from hydrogen to oxygen. 32
