Caesium (Cesium in American English), one of three metals that is in the liquid form at room temperature is most commonly used in atomic clocks. Historically, the most important use for cesium has been in research and development, primarily in chemical and electrical applications. It is also used in photoelectric cells.
What else can I help you with?
Does caesium have any unusual properties?
Caesium is the most reactive metal and has a very low melting point. It is also known for its high electrical conductivity, making it useful in some specialized applications like atomic clocks. Additionally, caesium has the most stable isotope, caesium-133, which is used to define the duration of one second.
What are the three most reactive metals?
Francium, caesium, rubidium
Why cant other alkali metals be substituted?
Alkali metal atoms can often be substituted by other atoms under the right conditions An example is Caesium in Caesium Chloride. By heating Caesium chloride with Calcium metal, caesium is substituted by calcium and the caesium can be distilled off at about 700oC under vacuum. This seems surprising, particularly given the higher reactivity of caesium, but the greater lattice energy of calcium chloride makes this the energetically preferred product over caesium chloride and drives the reaction. (As an aside, this was the most terrifying reaction that I ever did in a lab because of the high temperature caesium that is produced...)
When was caesium discovered?
Caesium was discovered in 1860.
Is caesium viscous?
Caesium is a solid metal.
What are the uses of caesium?
you use it for yourself
What is colour of caesium chloride?
Caesium chloride is a colorless crystalline solid. Its appearance is similar to common table salt.

Which of the elements in Group 1 are the most reactive?
it is caesium.
What is caesium used for now?
Caesium is a very volatile and reactive metal that spontaneously combusts in air, and reacts vigorously in water. This makes it difficult for people to utilize caesium for much as a metal, however the compound caesium formate is most widely used for drilling liquids. Some atomic clocks are also known to be caesium-based.
What are the most liquid isotopes of caesium?
Caesium hasn't liquid isotopes.The melting point of caesium is 28,5 oC.
What are the three most reactive metals?
Francium, caesium, rubidium
What is the most active metal besides francium?
The next is caesium.
What is a common ionic charge for caesium?
Cesium loses just one electron to form Cs+
What is atomic number 55 used in atomic clock for accuracy?
The atomic number 55 refers to the element caesium. Caesium atomic clocks use the natural resonant frequency of caesium atoms to measure time accurately. By measuring the vibrations of caesium atoms, these clocks can maintain incredibly precise timekeeping.
What is the word equation for caesium reacting with water?
Caesium + water ------> Caesium hydroxide + Hydrogen
