Silver chloride. (The compound is ionic. No charges required, silver is almost always a +1 charge.) Hope it helps.
Pb is a compound.
Yes, hydrogen gas is a compound. It is made up of molecules which consist of two atoms of hydrogen, an element. It just happens that the same name is used for the gas as for the element.
Ag is the chemical symbol for silver, which is an element. It is not a compound.
This is sodium sulphate.
Na2 is not a compound. When you see a formula containing Na2, it means the compound contains 2 Sodium ions.
If you mean the name of the element with the symbol F, it is Flourine
determined using the chemical formula of the compound. The chemical formula provides the type and ratio of elements present in a compound. After determining the chemical formula, one can calculate the exact number of atoms of each element in a unit of the compound using stoichiometry.
Na2 does not stand for anything by itself, because Na2 does not exist. Na2 would be part of a compound, such as Na2S or Na2O, in which case it means two sodium ions bonded with one sulfide ion or one oxide ion.
