In atomic form (as opposed to being an ion), cesium-137 has 55 electrons, just as all cesium atoms have.
Cesium-137
Proton = 1 Neutron = 1 Electron = 0.00054
It's not just Cesium 137. Of the 3000 or so known isotopes, MOST undergo radioactive decay. Only a fairly small percentage of the isotopes are stable. Usually, stability is achieved when the amount of neutrons, compared to the amount of protons, is "just right" - not too few, not too many. For the heavier elements (beyond lead), stability is no longer possible for ANY isotope.
The atomic number of barium is 56. So there are 56 protons and 56 electrons.
Cs-137 undergoes beta decay to transform into Ba-137. In this process, a neutron within the Cs-137 nucleus is converted into a proton, a beta particle (electron) and an antineutrino are emitted, resulting in the formation of Ba-137.
Only if it loses two neutrons
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
there are 55 protons Cs in the periodic table .
Oh, dude, cesium-134 has 55 protons and around 79 neutrons. It's like the cool kid at the periodic table party, just hanging out with its atomic number of 55 and atomic mass of around 134. So, yeah, it's got its protons and neutrons chillin' like, "What's up, we're cesium-134."

Barium has an atomic number of 56 and a mass number of 137 amu
The half-life of cesium-137 is about 30 years. This means that it takes 30 years for half of a sample of cesium-137 to decay into a more stable element.
The mass of 1 curie of cesium-137 is approximately 3.7 grams.
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.
Ceasium is a metal element. Atomic mass of it is 133.
