Anions, or negatively-charged ions, are formed when a metal loses electrons, and a nonmetal gains those electrons. An ionic compound is created when the electrostatic attraction between the positives and negatives brings the particles together.
No, an anion does not always form a covalent bond. An anion can form both ionic and covalent bonds depending on the nature of the element it is bonding with. In an ionic bond, an anion will typically form a bond with a cation through the transfer of electrons, while in a covalent bond, an anion will share electrons with another element.
Fluorine will typically form a fluoride anion by gaining one electron to complete its octet and achieve a stable electron configuration. Fluorine is a nonmetal and tends to gain electrons rather than lose them to form an anion.
Nitrogen will gain three electrons to form a nitride anion with a charge of -3.
Fluorine (F) is the most likely to form an anion because it is in Group 17 of the periodic table and readily gains an electron to achieve a stable octet configuration.
Scandium is a cation because it tends to lose electrons to form a positive charge.

The carbonate anion is CO32-.
Fluorine will typically form a fluoride anion by gaining one electron to complete its octet and achieve a stable electron configuration. Fluorine is a nonmetal and tends to gain electrons rather than lose them to form an anion.
A non metal must gain from 2 to 3 electrons to form an anion.
A non metal must gain one or two electrons to form an anion
Br is an anion. It is called bromide and is the ion form of the element bromine.
Nitrogen will gain three electrons to form a nitride anion with a charge of -3.
Chloride (Cl-) is the anion of chlorine.
Fluorine (F) is the most likely to form an anion because it is in Group 17 of the periodic table and readily gains an electron to achieve a stable octet configuration.
Xenon obeys octet rule and has a stable electronic configuration. So, xenon does not form any anion.
Scandium is a cation because it tends to lose electrons to form a positive charge.
Oxygen itself is not an anion, as it is a neutral atom when not ionized. However, when oxygen gains two electrons, it forms the oxide ion O2-, which is an anion.
