Physical properties of metal.
Hard to touch.
Lustrous - they have shiny surface
Sonorous- they produce ringing sound.
Malleable - they can be beaten into thin wire
Good conductor of heat and electricity.
Example - iron copper .
Potassium sodium and mercury are soft metal

[@ramjiwanmishra6466]

Sir please can you explain me heat conductivity and electrical conductivity please

[@Science_by_Armaan]

The ability of a material to pass an electric current through it is called electrical conductivity...
Jitna jayda electric current kisi material mei se paas ho payega vo material utna hi jayda good electrical conductor hoga... Or jo jitna jayda good electrical conductor hoga uski electrical conductivity bhi utni hi jayda hogi... Ya phir agar kisi material se current paas hi nahi ho paa raha hai toh uski electrical conductivity kam hogi...
Same heat ke case mei hota hai... Jo material jitna jayda heat ko paas karega uski heat conductivity bhi uss hisab se jayda hogi..
The ability of a material to pass heat through it is called heat conductivity...

[@jitendarvarma6076]

Sir mujhe melleable ka matlab nhi samajh me aaya aur bromine ke jagah carbon kyon dikh raha hai ?

Iodine and Carbon are the only lustrous non metals and
Graphite is the non metal which conducts heat and electricity

Yes... Carbon is lustrous in two forms... Diamond and Graphite!
You should know that Diamonds and Graphite are made of Carbon!

Sir is that Ductlile or Ductlitiy..?

[@Science_by_Armaan]

Both are almost the same!
Ductile is the conversation of materials (here metals) into thin/thick wires! The property which allows it to happen is called ductility!
