LOWEST MELTING POINT:
Since mercury melts at -38.8 degrees centigrade, it is liquid at room temperature. Mercury is used in thermometers because it expands as it is heated.
HIGHEST MELTING POINT:
The temperature must be 3,652 degrees centigrate before carbon will melt two-thirds as hot as the sun's surface.
RAREST ELEMENTS:
Astatine is the rarest element on Earth.
Rhodium is the scarcest metal in the world just 3 tonnes are mined every year.
HEAVIEST METAL:
A 33 cm3 cube of osmium weights 640 kg equivalent to ten people each weighing 64 kg, or a small car.
