Chlorine atoms have seven electrons in the outermost shell. As a result, one would expect chlorine to form ions with a charge of
A) +1.
B) +2.
C) 0.
D) -2.
E) -1.

Question

Quizplus · Accepted Answer

Chlorine atoms will tend to gain one electron in order to achieve a full outer shell of eight electrons (like the noble gas argon). This will result in a negative charge, so the ion formed will have a charge of -1.
