Question

An ion which has positive charge is called a:

Answer 1

Hint: A charged atom or molecule is known as a ion. There are two types of ion: positive ions (cation) and negative ions (anion). Negatively charged ions are called anions and positively charged ions are called cations.

Complete step by step answer:
Ion: An ion is a charged atom or molecule. An ion can be positively charged or it can be negatively charged. The atoms or molecules which have no charge or zero charge are not considered as ions.
Positively Charged ions are known as cations and the negatively charged ions are known as anions.
When the total number of electrons and protons differ from each other then it gives birth to an ion. If an atom or molecule releases electrons, it acquires positive charge over it and if an atom or molecule gains electrons then it acquires negative charge over it.
In easy language we can say if the number of protons is greater than the number of electrons in an atom or molecule then it is then it is a cation and if the number of electrons is greater than the number of protons then it is an anion.
So from the above discussion we can conclude that an ion which has positive charge is called a cation.

Note:
Ions are very useful in our daily lives and for chemical purposes. Ionic liquids are one of the examples of usefulness of ions in chemistry. These ionic liquids are used in chemical reactions and in future they have a lot use as organic solvents.
