ALEKS: Naming binary ionic compounds

[@ionicformula5771]

question, for PbI2 and PbI4, i'm supposed to put lead(ii) iodide and lead(iv) iodide respectively on aleks, but lead is not a part of the box that you have circled for indicating charge may i ask why this is so?

I ran into the same thing. I'd like the explanation of this too please!

@@candacerobles8463 same thing for tin. I think tin and lead are an exception

@@candacerobles8463 did you ever figure it out?

I ran into the same thing. It's so confusing because ALEKS states that it's for transition metals only and when you click on Lead on the ALEKS periodic table, it literally says metal and not transition metal.
