Atom contains:
Protons which are Positively charged
Electrons which are Negatively charged
Neutrons which are Neutral
In an atom, the number of protons is equal to the number of electrons .
So the positive and negative charges are balanced out
Ions are formed when atoms lose or gain electrons .
In formation of ions;
- Cation : When an atom loses an electron ,
The negative charge reduces .
Thus it becomes positively charged - Cation, because;
The number of positively charged protons becomes more than negatively charged electrons
- Anion : When atom gains an electron ,
The negative charge increases .
Thus it becomes negatively charged - Anion, because;
The number of negatively charged electrons becomes more than positively charged protons
