- Properties of Metals and Non-metals: Metals and non-metals have distinct physical and chemical properties that differentiate them from one another. Metals are generally good conductors of heat and electricity, have high thermal and electrical conductivity, and are ductile and malleable. Non-metals, on the other hand, are poor conductors of heat and electricity, have low thermal and electrical conductivity, and are generally brittle.
- Extraction of Metals: The extraction of metals from their ores is an important process in the production of metal products. The process of extraction involves a series of steps, including the removal of impurities from the ore, the reduction of the metal from its compound form, and the purification of the metal. Different methods of extraction are used for different metals, depending on their reactivity and the nature of their ores.
- Reactivity series: The reactivity series is a list of elements in order of their reactivity, from the most reactive to the least reactive. The reactivity series is useful in predicting the type of reaction that will occur when a metal reacts with an acid or a non-metal, as well as in the extraction of metals.
- Uses of Metals and Non-metals: Metals and non-metals have a wide range of uses, both in industry and in everyday life. Metals are widely used in construction, transportation, electrical and electronic applications, and in the production of alloys. Non-metals, on the other hand, are used in a variety of applications, including in the production of fertilizers, in the manufacture of plastics, and as fuels.
