Page 2: Octet Rule and Ion Formation
This page explores the octet rule and its importance in chemical bonding, along with ion formation processes.
Definition: The octet rule states that atoms tend to gain, lose, or share electrons to achieve eight valence electrons, similar to noble gases.
Highlight: The duet rule is an exception applying to H, Li, and Be atoms, which seek two valence electrons instead of eight.
Example:
- Calcium (Ca) loses two electrons to form Ca²⁺
- Chlorine (Cl) gains one electron to form Cl⁻
Vocabulary:
- Cation: Positively charged ion formed by losing electrons
- Anion: Negatively charged ion formed by gaining electrons

Page 3: Metallic Bonding and Properties
This page details metallic bonding and its unique properties through the sea of electrons model.
Definition: Metallic bonds involve delocalized valence electrons moving freely around fixed positive metal ions.
Highlight: The sea of electrons model explains key metallic properties:
- Lustrous appearance
- Heat conductivity
- Electrical conductivity
- Malleability
- Ductility
Example: Magnesium (Mg) has stronger metallic bonds than sodium (Na) due to more delocalized electrons, resulting in a higher melting point.
Vocabulary:
- Malleability: Ability to be hammered into sheets
- Ductility: Ability to be drawn into wires
- Delocalized electrons: Electrons that are not bound to specific atoms

Page 1: Types of Chemical Bonds
This page introduces the fundamental concepts of chemical bonding, explaining how valence electrons interact between different types of atoms.
Definition: Chemical bonds form when valence electrons of neighboring atoms are transferred, shared, or pooled together.
The page outlines three main types of bonds:
Highlight: The three main types of chemical bonds are:
- Ionic bonds
- Covalent bonds
- Metallic bonds
Example: Table salt (NaCl) demonstrates ionic bonding, water (H₂O) shows covalent bonding, and sodium metal (Na) exhibits metallic bonding.
Vocabulary:
- Formula unit (f.u.): The smallest representative unit of an ionic compound
- Electron sea model: Describes freely moving electrons in metallic bonds
