D
Alkali metals
Verified step by step guidance1
Understand that ions are atoms or molecules that have gained or lost electrons, resulting in a net charge.
Recall that elements tend to form ions to achieve a stable electron configuration, often resembling the nearest noble gas configuration.
Recognize that nonmetals typically gain electrons because they have higher electronegativities and are closer to filling their valence shell, thus forming negatively charged ions called anions.
Contrast this with metals, such as alkali metals and transition metals, which tend to lose electrons and form positively charged ions called cations.
Note that noble gases are generally inert and do not commonly form ions because they already have a full valence shell.
