- Heavy, silvery d-block metal
- One of six chemical elements that are liquid at or near room temperature and pressure.
- The only metal that is liquid at standard conditions for termperature and pressure with a melting point of −38.83 °C and boiling point of 356.73 °C, mercury has one of the narrowest ranges of its liquid state of any metal.

Hi Debbie,
ReplyDeleteI think that dentists aren't using mercury containing substances anymore. They found that people were getting mercury poisoning from their fillings! I had mine taken out years ago, luckily!
I wonder how non-mercury thermometer work? I think they have found alternatives, for instance in home thermometers, but I don't know what they are. Also, wondering why mercury is used in thermometers if it has a narrow temperature range in its liquid state...
