Open Ended

Recite a property referred as metallic character.

Metallic property

•  usually solid under normal conditions

• typical high luster

• good electric conductivity, which decreases by temperature increase

• malleable

• ductile

Face centered cubic lattice

• the most malleable metals

• e.g. silver, gold and aluminium

Hexagonal lattice

• the brittle (rideg) metals

• e.g. magnesium, zinc and nickel

Body centered cubic lattice

• no general properties

• the malleable depends on the exact element

• e.g. iron, sodium or potassium.
