About Mercury
Mercury is a heavy, silvery-white liquid metal known since ancient times. Mercury and its compounds are highly toxic, causing neurological damage. Dental amalgam containing mercury was once common but has been largely phased out due to health and environmental concerns.
Gebruiks & Programme
Fluorescent lighting, scientific instruments (being phased out), artisanal gold mining, and industrial chemical processes.
Fun Fact
Mercury is so dense that a cannonball would float on its surface.
