Physical Properties of Metals and Non-metals
Metals are generally lustrous, malleable, ductile, and good conductors of heat and electricity. Non-metals, on the other hand, are non-lustrous (except iodine), brittle, and poor conductors (except graphite).
Major Topics for HSLC 2027
- Chemical Properties: Reaction with oxygen, water, acids, and other metal salts.
- Reactivity Series: Understanding why some metals are more reactive than others.
- Ionic Compounds: Formation and properties of compounds formed by the transfer of electrons.
- Metallurgy: Extraction of metals from their ores and refining processes.
- Corrosion and Prevention: Methods like galvanization, alloying, and painting to protect metals.
