Atomic number is a term used for chemical elements not for compounds.
NH4Cl is ammonium chloride.
The oxidation number of the ammonium ion is +I.
Hydrogen chloride is not an element; it is a compound and has no atomic number!
Gently heat - ammonium chloride will sublime on a cold solid surface
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.
NH4Cl is ammonium chloride.
The oxidation number of the ammonium ion is +I.
Ammonium is a polyatomic ion, not an element and thus it does not have an atomic number. It is composed of nitrogen and hydrogen and has the formula NH4+. Nitrogen has the atomic number 7. Hydrogen has the atomic number 1.
Hydrogen chloride is not an element; it is a compound and has no atomic number!
Ammonium nitrate is NH4NO3 Ammonium chloride is NH4Cl
