Question

1. Define malleability
2. Define ductility
3. Write the difference between physical properties of metals and non-metals.
4. Write the name of metals
(a) Liquid at room temperature
(b) Can we cut with knife
5. Write the name of any two non-metals.​

Answer 1

Answer:

malleability is a property of metals by which they can beten into thin sheets

ductility :metals have a property that they can be drawn into thin wires

metals are ductile and non metals are non ductile

metals are malleable and non metals are non malleable

metals are good conductor of heat and electricity whereas non metals are poor conductor of heat and electricity

metal liquid at room temp is mercury

potassium and sodium can cut with knife

non metals:hydrogen and nitrogen
