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 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.
Is caesium soluble?
Caesium react with water.
What are the uses of caesium?
you use it for yourself
Put the metals caesium calcium and potassium in order of reactivity most reactive first?
Magnesium, Iron, Copper. Most reactive - least reactive.
What is the most metallic element after francium?
This element is caesium.
Which of the elements in Group 1 are the most reactive?
it is caesium.
What is caesium?
Most likely Ceasium is a common misspelling of the name for the 55th element: Caesium or Cesium, symbol Cs.(The misspelling can be understood when written phonetically after the correct pronounciation: "see-zee-əm" . It should not be pronounced as "kee-zee-əm" as would be expected from -the correct- spelling 'CAE...')
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.
Cs-OH common name?
CsOH is a chemical compound called Caesium Hydroxide.
What is the most active metal besides francium?
The next is caesium.
What are the three most reactive metals?
Francium, caesium, rubidium
What are the chemical symbols for lead gold plutonium and cesium?
Lead: Pb Gold: Au Plutonium: Pu Caesium: Cs The more common spelling is caesium, although cesium can be used.
Which elements radium lead iodine neon and caesium would be most likely to bond with other atoms?
Caesium (Cs), since has the lowest electronegativity
