This PowerPoint presentation aims to help students in the lesson of chemical bonding.

1. Welcome to my
class

2. Chemical Bond
A chemical bond involves
atoms combining to form
chemical compounds and
bring stability to the
resulting product.

3. Types of
chemical
Bond

4. • Involves the transfer of electrons from one atom to another
• Formed between a metal and nonmetal with sharp
electronegativity difference so that the nonmetal can
attract the electrons from the metal
Ionic Bond

5. • The covalent bond is a bond formed when two atoms share
one or more electron pairs. Each atom contributes an equal
number of electrons towards the bond formation.
• This happens in non metals.
covalent Bond

6. Two types of covalent bond

7. • A polar covalent bond exists when atoms with different
electronegativities share electrons in a covalent bond
Polar covalent Bond

8. • A type of chemical bond that is formed when electrons are
shared equally between two atoms.
Non polar covalent Bond

9. • Metallic bond' is a term used to describe the collective
sharing of a sea of valence electrons between several
positively charged metal ions.
