Most thermometers used to contain Mercury until it was found to be toxic.
Mercury (Atomic number 80) is still used in some thermometers.
We still use colored alcohol for our liquid in everyday thermometers.
Thermometers used to have Mercury in them because it is very temperature reactive and a liquid across most temperatures measured in everyday life. However, this practice has been discontinued due to the health risks associated with contact with mercury from broken thermometers; most analog thermometers today use colored ethanol as the measuring fluid.
It was used because it is a liquid that expands and contracts to a usable degree when heated or cooled.

Mercury is used in thermometers.
Mercury is a liquid metal used in thermometers. However, it becomes a solid at -37.9 F and it can cause mercury poisoning if ingested or inhaled. Therefore, most theremometers use ethyl-alcohol or a plastic strip covered with liquid crystals (called a liquid crystal thermometer).

Mercury (Atomic number 80) is still used in some thermometers.
For non-electronic thermometers , you will either see a red liquid or a silver liquid. The 'Red liquid' is a coloured alcohol. The 'Silver liquid' is mercury.

What is the new liquid used in athermometer than mercury?
Achohol, usually. Older thermometers use mercury, but that is too dangerous.
Mercury would be the dangerous liquid used in thermometers. Many modern thermometers are made without mercury for safety reasons, but if a thermometer breaks and you're not sure, it's better to be careful with the cleanup.
