I want to thank your team (Jeff) for finding a new writer when you were unable to reach my existing writer to revise my paper. I appreciate your professionalism and efforts. Thanks
##””_ 55^137Cs -> “”_ 56^137Ba + “”_”-1″^0beta##
Cesium-137 has an of 55, so is written as
##””_55^137Cs##.
It is also a ##beta##-emitter, which means it undergoes ##beta##-decay by a neutron decaying into a proton, releasing an electron.
Protons and neutrons have the same mass, so the doesn’t change. The atomic number increases by one, because one more proton is formed.
Because the atomic number changes, this is a new element, number ##56##, barium, or
##””_56^137Ba##
In the form of an equation, this is written as
##””_ 55^137Cs -> “”_ 56^137Ba + “”_”-1″^0beta##
This video shows a sample of Cs-137 being tested by a hand-held detector.
