Question

1.WHICH AMONG THE FOLLOWING IS NOT THE PROPERTY OF METAL 1.LUSTRE 2.MALLEABLE 3.DUCTILE 4.BRITTLE

Answer 1

Answer:

4) Brittle

Properties of Metal :

• Lustrous
• Ductile : Can be drawn into wire
• Malleable : Can be turn into thin sheets
• They are hard
• They are good conductor of heat.
• They are good conductor of electricity.
• They are mostly solid.
• The density of metals in high.
• They form basic oxides

Properties of Non-metal :

• Brittle
• Non ductile
• Non malleable
• They are not hard
• They are in solid, gas and liquids states.
• The density is low.
• They are not good conductors of heat and electricity.
• They form acidic oxides.
