Understand that ions are atoms or molecules that have gained or lost electrons, resulting in a net electrical charge.
Recall that anions are specifically ions that carry a negative charge, which means they have gained one or more electrons.
Contrast anions with cations, which are ions with a positive charge formed by losing electrons.
Recognize that neutral atoms have equal numbers of protons and electrons, so they do not carry a charge.
Identify that molecules containing both positive and negative charges are called zwitterions or dipolar ions, which is different from the definition of anions.
