What are metals?
Metals are those substances that gain positive charge by losing electrons. Ex-Mercury, gold etc. They are malleable, ductile, sonorous, hard etc.
What are non-metals?
Non-metals are those substances that gain negative charge by gaining electrons. Ex-chlorine, phosphorus. They are non-malleable, non-ductile, non-sonorous and so on.
- Malleability : The property of the metals by which metals can be hammered into thin sheets is called malleability.
- Ductility : The property of the metals by which metals can be drawn into thin wires is called ductility.
- Sonority : The property of the metals by which metals produce sound when we strike on them.
