Caesium was first identified in 1860 by Robert Bunsen (of Bunsen burner fame), and Gustav Kirchhoff (of electrical circuits fame), in the course of studying flame photometry. [This same pair also discovered rubidium.]Caesium was named after the Latin word for blue, its flame colour. This metal melts below body temperature at 28.4oC. It also has some nasty radionuclides.
Caesium burns with a blue-violet color in a flame test. This distinct coloration is due to the excitation of its electrons, which emit light at specific wavelengths when they return to their ground state. The flame test is a useful method for identifying the presence of caesium in a sample.
The blue flame.
The flame is white and very luminous.
I cant

Caesium chloride is a colorless crystalline solid. Its appearance is similar to common table salt.
To identify the presence of certain metal ions, such as sodium and caesium.
The colour turns brick Red .
Potassium is the only metal (alkali metal) where a flame is present. Lithium and sodium fizz but there is no flame. Caesium, francium and rubidium all explode on contact with water.
You get and orange - yellow colour.
I suppose that the flame test was not applied to californium.
The blue flame.
Blue?
yellow
Barium ions give off a green colour when heated in a flame.
well , the colour of potassium chloride is a lilac colour :) hope this helps
