Which of the following is an example of an anion?
A
Cl^-
B
Mg^{2+}
C
Na^+
D
K^+
Verified step by step guidance1
Understand that anions are negatively charged ions, while cations are positively charged ions.
Look at the charge on each ion: Mg^{2+} has a 2+ charge, Na^{+} has a 1+ charge, K^{+} has a 1+ charge, and Cl^{-} has a 1- charge.
Identify which ion has a negative charge, since that will be the anion.
Recognize that Cl^{-} is the only ion with a negative charge, making it an anion.
Conclude that Cl^{-} is an example of an anion, while the others are cations.
