, METALS
Those elements which form positive ions by losing electrons are
called Metals.
Physical Properties of Metals -
1. Good Conductor of Heat and Electricity.
2. High melting and Boiling Point
3. Solid at room temperature except mercury (liquid)
4. Are Sonorous (means they produce a sound on striking)
5. Are Malleable, i.e., they can be hammered into thin sheets.
6. Are Ductile (means they can be used to make wires)
Gold is the most ductile metal means wires of gold can be
made easily because gold is very soft for bending.
But we can’t use Wires of Gold in our Home (क्यं�ू क Gold
