McMurry – Test Bank Fundamentals of General, Organic, and Biological Chemistry, 7e (McMurry) Chapter 3 Ionic Compounds 1) A positively charged particle formed by loss of one or more electrons from an atom is called a(an) 1. A) anion. 2. B) cation. 3. C) isotope. 4. D) nucleus. 5. E) proton. Answer: B Diff: 1 Section: 3.1 2) A small negatively charged particle formed when an atom gains one or more electrons is called a(an) 1. A) anion. 2. B) cation. 3. C) isotope. 4. D) nucleus. 5. E) proton. Answer: A Diff: 1 Section: 3.1 3) When an atom donates an electron, that electron 1. A) is lost for all time. 2. B) is acquired by another atom which becomes an anion. 3. C) is acquired by another atom which becomes a cation. 4. D) neutralizes a proton to form a neutron. 5. E) pairs with another electron to form a covalent bond.
