For Tungsten it is W+3 or W+6.
the chemical symbol for boron ion is B+++
The chemical symbol for a silver ion is Ag+.
The chemical symbol for a sodium ion is Na+.
The chemical symbol for an ammonium ion is NH4+.
The chemical symbol for potassium ion is K+.
the chemical symbol for boron ion is B+++
The sulfite ion is SO32- It is not to be confused with sulfate, SO42-
Al3+ ion
Formula: HCl
The chemical symbol for the most stable ion of barium is Ba2+.
The chemical symbol for hydroxide ions is OH-.
the number of protons stay the same in every element (i think). So the number of protons is the atomic number. Therefore, this is tungsten (W). The electrons and nuetrons are the only thing that change.
