Metals and Non-metals” introduces students to the fundamental physical and chemical differences between these two broad categories of elements, including their appearance, hardness, conductivity, malleability, ductility, and behavior when reacting with oxygen and water, as well as their diverse applications in daily life. Key distinctions are that metals are typically hard, lustrous, malleable, ductile, and good conductors, while non-metals are often dull, brittle, and poor conductors

Metals:-
- They are lustrous
- They are hard
- They are malleable
- They are sonorous
- They are ductile
- They are good conductors of heat & electricity
Eg:- Iron, Copper, aluminium
Non Metals
- They are dull in appearence
- They are not very hard
- They are not mettable
- The are not ductile
- They are not sonorous
- They are the conductors of heat & electricity
Eg:- Carbon, Sulphur, Phosphorus
Displacement reactions are those where a more reactive element replaces a less reactive element from its compound. For metals, this means a highly reactive metal displaces a less reactive metal from its salt solution, like zinc displacing copper from copper sulfate. While non-metals also undergo displacement, the principle remains the same: a more reactive non-metal can displace a less reactive non-metal.
