Anions are atoms or groups of atoms that have a negative electric charge. [1] An anion has more electrons in its atomic orbitals than it has protons in its atomic nucleus.

Mar 3, 2020 · Get the definitions of cations and anions. See examples of the two types of ions, learn how they are different, and see periodic table trends.

Oct 3, 2024 · Anions are negatively charged ions that form when atoms gain electrons, and a list of anions includes common ones like chloride, sulfate, and nitrate.

Anions are negative ions that are formed when a nonmetal atom gains one or more electrons. Anions are so named because they are attracted to the anode (positive field) in an electrical field.

Aug 27, 2025 · Anions are ions with a net negative electrical charge. This occurs when an atom or group of atoms gains electrons. Electrons are negatively charged subatomic particles, so adding them to a …

Dec 1, 2025 · Anions are negative ions that are formed when a nonmetal atom gains one or more electrons. Anions are so named because they are attracted to the anode (positive field) in an electric …

Anions are negatively charged ions formed by gaining electrons, while cations are positively charged ions formed by losing electrons. Metals typically form cations, while non-metals form anions.

Roman numeral notation indicates charge of ion when element commonly forms more than one ion. For example, iron(II) has a 2+ charge; iron(III) a 3+ charge.

Anions are the negative ions formed from the gain of one or more electrons. When nonmetal atoms gain electrons, they often do so until their outermost principal energy level achieves an octet.

Opposite electric charges are pulled towards one another by electrostatic force, so cations and anions attract each other and readily form ionic compounds. Ions consisting of only a single atom are …
