METALS & NON METALS in 30 Minutes || Mind Map Series for Class 10th
Physics Wallah Foundation・2 minutes read
Metals possess specific physical properties like malleability, conductivity, and sonorousness, while non-metals lack these characteristics and can form acidic oxides. The reactivity of metals determines their behavior in reactions with water, acids, and salt solutions, leading to the formation of ionic compounds through the transfer of electrons.
Insights
- Metals are characterized by being malleable, ductile, good conductors of heat and electricity, having a luster, and being generally solid at room temperature, with exceptions like mercury.
- The extraction of metals involves a process of categorization based on reactivity, conversion of compounds to oxides for easier extraction, followed by reduction and electrolytic refining for purification, with methods like roasting and calcination employed to facilitate extraction.
