Ionic and Covalent Bonding
IONIC BONDING
An ionic bond is a chemical bond formed by the electron attraction between positive and negative ions
COVALENT BONDING
Covalent Bonds are chemical bonds formed by the sharing of a pair of electrons between atoms
Examples:
Ionic Bond: NaCl
Total Number of Electrons: 8
There are no extra electrons so the drawing is done.
Covalent Bond: HCl
Total Number of electrons : 8
Covalent Bond: FCl
