Chemistry – Chemical Bonding

Chemical bonding is the process by which atoms combine to form molecules


or compounds. Bonds form because atoms want a stable arrangement of
electrons, usually a full outer shell.

Types of Bonds

1. Ionic Bond

o Formed when one atom transfers electrons to another.

o Usually between metals and nonmetals.

o Example: Sodium chloride (NaCl).

2. Covalent Bond

o Formed when atoms share electrons.

o Usually between nonmetals.

o Example: Water (H₂O).

3. Metallic Bond

o Formed between metal atoms.

o Electrons are shared in a “sea of electrons,” allowing metals to


conduct electricity and be malleable.

Key Vocabulary

 Molecule: Two or more atoms bonded together.

 Compound: Substance made of two or more different elements


chemically bonded.

 Electronegativity: How strongly an atom attracts electrons in a bond.

 Polar Bond: Unequal sharing of electrons, causing partial charges.

Why It’s Important


Chemical bonding explains the structure and properties of all substances. It
is essential for understanding chemistry in everyday life, from water and
food to medicines and materials.
