An ion is an atom or molecule which has lost or gained one or more electrons which makes it positively or negatively charged. A negatively charged ion is known as an anion. For more information, see the link below:

An ion is an atom or modules which have lost or gained one or more valance electrons, giving it a positively or negatively charged. An ion consisting of a single atom is called a monatomic ion.  As it turns out an atom contains a central nucleus which has protons and neutrons in it. Surrounding the central nucleus is a cloud of electrons. These electrons have an opposite electrical charge to the protons found in the center core. In a typical uncharged atom, there are an equal number of electrons and protons. Each positively charged proton is canceled out by one negatively charged electron. The electrons spin about the outside of the protons forming a type of electron cloud.

As said above an ion is an electrically charged particle which can gain or lose electrons.A positively charged ion is called a cation and a negatively charged ion is called an anion.

An ION is an electrically charged atom or atom group: An atom or group of atoms that has acquired an electric charge by losing or gaining one or more electrons.
 
You would find it facinating and very informative to do a web search for a website with examples and illustrations.

Hi Ajiiani!
 
An ion is an atom or molecule which has lost or gained one or more valence electrons, giving it a positive or negative electrical charge.
A negatively charged ion, which has more electrons in its electron shells than it has protons in its nucleii, is known as an anion (ana: Greek 'up') (pronounced /ˈænaɪən//; an-eye-on). Conversely, a positively-charged ion, which has fewer electrons than protons, is known as a cation (kata: Greek 'down') (pronounced /ˈkætaɪən//; cat-eye-on).
An ion consisting of a single atom is called a monatomic ion, but if it consists of two or more atoms, it is a polyatomic ion. Polyatomic ions containing oxygen, such as carbonate and sulfate, are called oxyanions.
Ions are denoted in the same way as electrically neutral atoms and molecules except for the presence of a superscript indicating the sign of the net electric charge and the number of electrons lost or gained, if more than one. For example: H+ and SO42−.

Ions are the charges positive and negative charges, when the atom loss or gain the charge and as a result the positive or negative charges are created.
