Mercury
Mercury's abbreviation is hg
Basic information
I chose to do mercury because I found it really interesting as it is a metal but also a liquid at room temperature.It does not match up with its abbreviation (hg).
Its original name is 'Hydragyrum' meaning 'Hydra' (watery) and 'gyrum' (silvery) which is why it's abbreviation is (hg). It was discovered in 1500 BC in Egyptian tombs.
This element looks like a metallic liquid
Mercury is used in thermometers, barometers, fluorescent lamps and batteries. I thought it was unusual because it is a liquid at room temperature and it is named after a Roman God.

Mercury is 13 times more dense than water and is even denser that lead. A cannon ball can float on a tub of mercury meaning that mercury is denser than a cannon ball.
