Verified step by step guidance1
Understand what an anion is: an anion is a negatively charged ion formed when an atom gains one or more electrons.
Recall that elements tend to form ions to achieve a stable electron configuration, often resembling the nearest noble gas configuration.
Recognize that nonmetals have higher electronegativities and a stronger tendency to gain electrons to complete their valence shell, thus forming anions.
Contrast this with metals, especially alkali metals and transition metals, which tend to lose electrons and form cations (positively charged ions).
Note that noble gases are generally inert and do not typically form ions because they already have a full valence shell.
