what are ions and what is chemical bonding and ionic bonding
Ions- These are the charged species formed by the gain or loss of electrons from atoms of an element.
The positively charged ions are called cations and negatively charged ions are called anions.
Chemical bonding is a process by which two or more atoms combine together to form molecule.
Ionic bonding – The atoms form ions by gaining or loosing electrons and are combined through electrostatic force of attraction.
