## Intramolecular Forces
*   Definition: Strong forces of attraction acting within a molecule that hold atoms together.

## The Three Main Types of Bonds
1.  **Ionic Bonding**: Transfer of electrons (giving and taking).
2.  **Covalent Bonding**: Sharing of electrons.
3.  **Metallic Bonding**: 'Sea of electrons' (free-flowing).

## Ionic Bonding
*   Occurs when one atom gives away electrons to another, creating oppositely charged ions.
*   **Example**: Table Salt (NaCl). Sodium loses an electron to Chlorine, forming a crystal lattice.

## Covalent Bonding
*   Atoms share pairs of electrons to achieve stability, typically between non-metals.
*   **Example**: Water (H₂O). Oxygen shares electrons with two Hydrogen atoms via single covalent bonds.

## Metallic Bonding
*   Electrons are delocalized and free to move throughout the structure.
*   Explains properties like electrical conductivity.

## Bond Strength Comparison
Comparison of Bond Dissociation Energy (kJ/mol):
*   Metallic (Sodium): 108 kJ/mol
*   Covalent (Diamond C-C): 348 kJ/mol
*   Ionic (Table Salt): 787 kJ/mol

## Conclusions
*   Ionic bonds create charged ions.
*   Covalent bonds maximize stability through sharing.
*   Metallic bonds allow free electron flow.
*   These forces dictate material properties like hardness and conductivity.
