1. Metallic Bond
IKATAN LOGAM

2. Teaching Learning Objectivers
The student can describe forming of metal bond.
The student can relate to physic properties of metal.

3. Metalic atoms tend to lose their outer shell
electrons and forming a positively charge.
The cations thus produced are held together by the forces of attraction between them and the negatively charged electrons.
These electrons are found in a common pool and are free to move between all the cations.
The metallic crystals consist of cations immersed in “sea” of electron that are freely moved.

4. This shows what a metallic bond might look like.
- A metallic bond occurs in metals. A metal consists of positive ions surrounded by a “sea” of mobile electrons.

5. Properties of Metal Often hard,
Have a high boiling point and melting point,
Good conductors of heat and electricity,
Have a shiny surfase (when polished).
