Praxis II: Chemistry Exam Prep

Correct Response: B. In this atom (ion), the electrons outnumber the protons by 1, so the atom (ion) has a net charge of –1. A is incorrect since this represents the total number of electrons and does not take into consideration the presence of the 6 protons. C is incorrect since it is the electrons that outnumber the protons, rather than the protons outnumbering the electrons. D is incorrect since 6 protons are present and the charge from all of these (+6) is offset as a result of the presence of 7 electrons.
