It depends on the thermometer. An old-style liquid thermometer might contain: * Mercury (silvery) * alcohol (usually dyed red or blue for visibility) * an alloy of sodium and potassium (silvery) * an alloy of gallium, indium, and tin (silvery) * any of a number of other things depending on the temperature range to be measured Electronic thermometers contain a thermocouple plus electronics to turn the potential generated by the thermocouple into a temperature reading.
Common household thermometers used to have mercury in them, but mercury is dangerous, so most thermometers nowadays only have very tiny amounts of it. Instead of mercury, they often use a substance called galinstan. See the Related Link below.
Mercury use to be the most commonly used fluid in thermometers. Now, because of concerns about the toxicity of mercury should it be released from a broken thermometer, they use red alcohol in most liquid thermometers.
usually mercury (quick silver) although now days it might be something else which is not toxic.
Often Mercury is in Thermometers because it is a liquid at room temperature and expands with heat. But due to the dangers associated with Mercury it is being used less.

the thermometers which are used to find your temperature
Most thermometers used to contain Mercury until it was found to be toxic.

Mercury (Atomic number 80) is still used in some thermometers.
There are several types of thermometers. Clinical thermometers are used to measure the body temperature of the patient. Ear Thermometers make it an accurate point to measure the body temperature. Pacifier thermometers are used to check the body temperature of babies or infants. Underarm thermometers are kept in the underarms to measure the body temperature. Not to mention the food thermometers that are often used for checking the heat of the oil or pop up to let you know when the meat is done.
Infrared thermometers or laser thermometers as they are someimes known are useful for measuring temperature under circumstances wprobe type sensors cannot be used .
Mercury is used in thermometers.
Mercury thermometers are rarely used, except in lab thermometers. For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
the thermometers which are used to find your temperature
Mercury is not used in thermometers, because mercury is poisonous.
In normal and some medical thermometers Mercury is used. That is why you may want to consider using electric thermometers which are more commonly used. They use no mercury.

Alcohole is not used for any thermometer only murcury (Hg) is used
Digital thermometers have replaced mercury thermometers because mercury is toxic. [Personal commentary: digital thermometers are not accurate and mercury thermometers are so how many people are being harmed by not knowing their temperature versus how many would be harmed by the mercury if accurate thermometers were still used?]
