Alkaline-earth elements form cations.
Fluorine is an element. Fluoride is an anion.
This is a polyatomic anion.
Oxygen is neither a cation nor an anion. It is a neutral element.
An anion is named using the base element with an -ide suffix. Ex: Br- (Bromine anion) is named bromide sulfur- sulfide, ect.
Yes, fluoride is an anion that is derived from the element fluorine.
A single element cation and single element anion form a binary ionic compound, where one element is a metal and the other is a nonmetal. The metal forms the cation by losing electrons, while the nonmetal forms the anion by gaining electrons. Examples include NaCl (sodium chloride) and KBr (potassium bromide).
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.

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.
The suffix "ide" at the end of the name of an element typically indicates that the element is in the form of an anion or a negatively charged ion. For example, chloride (Cl-) is the anion form of chlorine.
