It has to do with the structure of the mercury atom - having a single electron in it's outer most shell allowing it to lose an electron and become an ion.
There are several metals that are liquid at or near room temp. I think the weirdest is gallium. If the room temp. is in the 70's or 80's it is solid. If you put a solid piece of it in your hand, it becomes liquid (melting temp of gallium is 85.5 degrees Fahrenheit.
Hope this helps
I don't know...I think it has to do with density!
When it is hot there is less density and when it is cold density increases!
Did you learn this in science? I think I might ask my teacher this!
I think it shars simular traits with other metalsHow are a mercury barometer and a aneroid barometer alike and
haha do you mean the planet or the elementWhat are the distinguish properties of metals and non-metals?
