Caesium hasn't liquid isotopes.
The melting point of caesium is 28,5 oC.
Caesium and Xenon, with 36 isotopes each
At room temperature caesium and francium are solids.
This question is a non-sequitur. Viscosity is a property of liquids. Caesium is a solid at standard temperature and pressure. If you heated caesium until it was a liquid, the viscosity would decrease as you increased the temperature.
Some isotopes of xenon do undergo radioactive decay to caesium.
No most of them are not isotopes. Few elements exist as isotopes.
Caesium has a melting point of 28.4°C (83.2°F), which makes it one of only five elemental metals that are liquid at or near room temperature.
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.
it is caesium.
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.
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.
Celsius is a measurement of tempurature. Caesium is an element that is a liquid at room tempurature.
