This isotope is antimony-123, which has 51 protons (atomic number) and 72 neutrons (mass number - atomic number). It is a stable isotope of antimony found in nature.
The CAS number is 7440-21-3
Antimony trisulphide Sb2S3 is a compound and does not have an atomic number. Antimony does and so does sulfur - but not the compound
Antimony has 51 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in an antimony isotope = Mass number - 51
Silver's (Ag) CAS registry number is: 7440-22-4
Only chemical compounds have a CAS number.
