Cesium is silvery gold in color.
Cesium chloride is likely to be colorless or white in its pure form. Its crystals may appear colorless or slightly yellow due to impurities.
Its appearance is not known but i think it may be a colour like grey-green
Cesium Indium, as in indigo. (Cesium does burn with a blue colour too but it wasn't named for that trait.)
The compound formed between sulfur and cesium is called cesium sulfide.
If universal indicator is added to water after a reaction with cesium, the solution would likely turn purple or dark blue. This is because cesium reacts vigorously with water to produce cesium hydroxide, which is a strong base. The formation of this alkaline solution raises the pH, causing the universal indicator to shift toward the color that corresponds to higher pH levels.
cesium phosphide
Cesium Nitride
The cesium ion is called cesium ion or Cs+.
The correct name for the cesium ion is "cesium ion" or "Cs+ ion".
Cesium Chromate = Cs2CrO4
The formula for Cesium Peroxide is: Cs2O2
cesium will sink
