Anyone using this Zmaczynski Triangular Periodic Table Model for teaching....? Hows it different from the standard PT?

The Triangle PT is supposed to make it easier to see how orbitals fill. Personally, I do not like the Triangle PT. Some first year chemistry students might have a problem with the understanding of why s and p orbitals are promoted over d; however, once an energy diagram is used - they tend to get it. Now, the poor little first year kids do not have to totally grasp all of the importance and concepts of an energy diagram..... All I really expect for beginners is to have a basic understanding of how oribtals fill and how this relates to periodic trends.

Thanks Bill. Really helpful. I now better opt for the normal PT.

http://library.thinkquest.org/C0110203/othertables.htm This table was created to help students to easier see the manner in which orbitals fill. Personally, I do not like it. I think that a well explained periodic table enables students to very quickly grasp the orbital filling patterns and exceptions - which comes back in to play when explaining multiple oxidation states. The ZTP model cannot be used (I will admit no formal training with it) to explain multiple oxidation states.
