PHYSICAL PROPERTIES OF METALS AND ALLOYS

PHYSICAL PROPERTIES OF METALS AND ALLOYS

Constitution ​

Constitution - the or­dered arrangement of the metal atoms and their relation to each other to geometric form in solid crystals.​

​Lattice structures

​Solidity

​Almost all the metals are solid.

​Exception - mercury

​Melting and Boiling Points

• ​MP - the temperature at which a metal melts

• ​BP - the temperature at which the metal boils under normal atmospheric pressure

​Conductivity

• ​heat

• ​electricity

​Hardness

​ Not all  metals are hard. 

The  metals  sodium, potassium and lead are comparatively soft.

​Magnetism

​the magnetic for­ce exerted by a unit volume of a substance under standard ma­gnetizing force.

​

​Iron, cobalt and  nickel  are the only metals possessing considerable magnetism at room temperature
