Question

(a) What is an ion? Explain with examples.
(b) What is the nature of charge on (i) a cation, and (ii) an anion?
(c) name the cation and anion present in MgCl2. Also, write their symbols.
 


Solution

Answer :

(a) An electrically-charged atom (or group of atoms) is called an ion. it is formed by the loss or gain of an electron by an atom.
Ions are of two types: cations and anions.
For example, A sodium ion (Na+ ) is formed when a sodium atom loses one electron. A sodium ion is a cation.
A chloride ion (Cl ) is formed when a chlorine atom gains one electron. A chloride ion is an anion.

(b) (i) The charge on a cation is positive.   
     (ii) The charge on an anion is negative.

(c) The cation present in MgCl2  is a magnesium ion that is represented as Mg2+  and the anion present is a chloride ion that is represented by Cl.
