137Cs55 is the symbol for cesium 137.
You are looking for the symbol of cesium (Cs) and indication of its mass number. The mass number is the sum of the protons and neutrons. So if every atom of cesium has 55 protons, then the mass number of this isotope is 137. The mass number is indicated in superscript before the symbol: 137Cs
Ceasium is a metal element. Atomic mass of it is 133.
the density of cesium is 1.93 and its atomic # is 55 symbol Cs
From the Periodic Table, Caesium is 'Cs' .
Since the half-life of cesium-137 is about 30 years, 3 half-lives would have passed in 90 years. The first half-life would leave .5 mg of cesium-137. The second would leave .25 mg, and the third half-life would leave .175 mg of cesium-137.

Cesium-137 will react with chlorine to form cesium chloride. However it is highly radioactive so must be handled carefully, because of this it is often used to treat cancer patients and sterilize medical equipment and some foods.
