An ion is an atom or group of atoms that has an electrical charge from having either gained or lost electrons. An ion may have either a positive or a negative charge. An electron is a subatomic particle that carries a negative charge and is usually found in the orbitals of atoms and ions.
Anion/Anions.
Ions. Usually negative ions, but not always.
A Polyatomic ion is a covalently bonded group of atoms that has a positive or negative charge and acts as a unit
A polyatomic ion is held together by covalent bonds between atoms. They can be either positive or negative. For example, the ammonium ion, NH4+, has a positive charge, and the sulfate ion, SO42-, has a negative charge.
A polyatomic ion is a group of atoms with a charge.
Ions are formed when atoms have charges. Cations are species with positive charge. Anions are species with negative charge.

a tightly bound group of atoms that behaves as a unit and has a positive or negative charge
Anion/Anions.
It is an ion.
Ions.Cations are positively charged species. Anions are negatively charged species.
When an atom or group of atoms becomes electrically charged, it is referred to as an ion. If it has a positive charge (+) it is called a cation, and if it has a negative charge (-), it is called an anion.
In a covalent bond neither group of atoms would gain any charge since the electrons are "shared" between two atoms.
Ions. Usually negative ions, but not always.
polyatomic ions are those ions which carry more than one atom,we can say that a group of atoms having single charge( which may be positive or negative) are polyatomic ions.
