Physical Properties of Metals

Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include:

State:

Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).

Luster:

Metals have the quality of reflecting light from their surface and can be polished e.g., gold, silver and copper.

Malleability:

Metals have the ability to withstand hammering and can be made into thin sheets known as foils. For example, a sugar cube sized chunk of gold can be pounded into a thin sheet that will cover a football field.

Ductility:

Metals can be drawn into wires. For example, 100 g of silver can be drawn into a thin wire about 200 meters long.

Hardness:

All metals are hard except sodium and potassium, which are soft and can be cut with a knife.

Valency: Metals typically have 1 to 3 electrons in the outermost shell of their atoms.

Metalloids:

Metalloids have properties intermediate between the metals and nonmetals. Metalloids are useful in the semiconductor industry. Metalloids are all solid at room temperature. They can form alloys with other metals.
