Calcium chloride is a salt; calcium is the cation and chloride the anion.
Scandium is a cation because it tends to lose electrons to form a positive charge.
polyatomic anion
Iron can exist as both an anion and a cation, depending on its oxidation state. In its most common forms, iron is a cation with a positive charge.
Fluoride is an anion because it has a negative charge due to gaining an electron.
Silver is normally not a cation or an anion, it is an element. Once it becomes an ion however, it will become a CATION with a +1 charge (Ag^+).
Scandium is a cation because it tends to lose electrons to form a positive charge.
polyatomic anion
The PO4^3- ion is a polyatomic anion. It consists of a group of atoms with an overall negative charge.
An anion has gained electrons and therefore has a negative charge, while a cation has lost electrons and therefore has a positive charge.
An ion can be either a cation or an anion, depending on whether it carries a positive or negative charge, respectively. Cations have a positive charge because they have lost electrons, while anions have a negative charge because they have gained electrons.
An ion with a positive charge is called a cation, and has a superscript + sign to the right of it An ion with a negative charge is called an anion, and has a superscript - sign to the right of it
Silver is normally not a cation or an anion, it is an element. Once it becomes an ion however, it will become a CATION with a +1 charge (Ag^+).
An ion with a positive charge.-- opposite of an anion.
Iron can exist as both an anion and a cation, depending on its oxidation state. In its most common forms, iron is a cation with a positive charge.
Chloride is an anion. It carries a negative charge due to the gain of an electron.
If it has a positive charge it is a Cation. If it has a negative charge it is an Anion.
Silver forms a cation with a charge of +1, represented as Ag+.
