Which type of elements typically form positively charged ions (cations)?

Nonmetals

Metals

Noble gases

Halogens

Verified step by step guidance

Understand that ions are atoms or molecules that have gained or lost electrons, resulting in a net charge.

Recall that metals tend to lose electrons to achieve a stable electron configuration, forming positively charged ions called cations.

Nonmetals, on the other hand, usually gain electrons to form negatively charged ions called anions.

Noble gases are generally inert and do not typically form ions because they already have a full valence shell.

Halogens are nonmetals that tend to gain electrons, forming anions rather than cations.
