7440-36-0 is the CAS number of antimony.
The CAS number is 7440-21-3
The CAS registry number of iron (Fe) is 7439-89-6
The CAS number for potassium plumbite is 6353-03-3.
Antimony (Sb) has the atomic number of 51. The atomic number is the same as the number of protons in the atom (an the same as the number of electrons in the neutral atom).
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
Only chemical compounds have a CAS number.
The CAS number for bauxite is 1318-16-7.
Silver's (Ag) CAS registry number is: 7440-22-4
Each neutral atom of antimony contains 51 electrons, the same as the atomic number of antimony.
