Probably sulfur, not sulphate.
The atomic number of sulfur is 16.
ammonium sulfate is a compound not an element and therefore has no atomic number. Perhaps you were thinking of molecular weight. But that is a totally different concept.
Sulfate is a polyatomic ion, SO42-, meaning it is a covalently bonded substance that carries a charge. Thus, it does not have an atomic number. Atomic numbers are assigned to pure elements, such as Sulfur (16) and Oxygen (8).
In the formula unit for mercury (I) sulfate, there are two atomic symbols for mercury, one atomic symbol for sulfur, and four atomic symbols for oxygen. This gives a total of seven total atoms.
the answer is that it is called a atomic number.
Ionic containing barium cations and sulfate anions the sulfate anion is poly atomic and contains 4 sulfur oxygen covalent bonds.
ammonium sulfate is a compound not an element and therefore has no atomic number. Perhaps you were thinking of molecular weight. But that is a totally different concept.
There is no atomic mass - sulfate is a polyatomic ion. The molecular mass, however, is 80.1 g/mole.

Atomic number is a property of an atom (An Element) and not a chemical compound. Sodium chloride is a compound and thus it can not have any atomic number. Atomic number is the number of protons present in the nucleus of the atom of an element. e.g. Carbon has six protons in its nucleus, therefore its atomic number is six. However, sodium chloride has two different elements as its constituents and therefore one can not determine its atomic number.
In the formula unit for mercury (I) sulfate, there are two atomic symbols for mercury, one atomic symbol for sulfur, and four atomic symbols for oxygen. This gives a total of seven total atoms.
the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
this elemnt has an atomic number that is double the atomic number of silicon?
Subtract the atomic number from the atomic weight.
