Preview of Periodic Table v2.0
Posted on 27 August 1998, 18:04 GMT

As the new school year rapidly approaches, the need for math & science programs is increasing. However, good assembly programs are hard to come by.

Ahmed El-Helw will try to fill that gap when he releases a total rewrite of his Periodic Table program for AShell83 and SOS sometime in September. This program will include information such as the element name, atomic number, symbol, and atomic mass. The electron configuration of each element may also be included.

I've used your first version of the periodic table for the TI-86 and I have to say, this one is much better. You NEED to port this to the 86 soon, because school has already started for me and I'm in the science club. I need a program that will help me study the elements. Thanks a bunch...

Ten four. Cartman out...

As a matter of fact, I got this idea from the 86 program, Elements. This program by Andrew Hockman of Stargun Production [I think that's what it was], rocks, and so I decided to "clone" it for the 83. I'll probably port to the 82 though. The 86 has a good one already ;) Unless I add something it doesn't have...

What would be nice is a Usgard Periodic Table that includes electron configuration. The two out for the 85 don't have anything close.

Electron configurations are something that to me seems more efficiently calculated than stored. Given the atomic number, it should be easy to write a program that spooes out the electronic configuration for an element. All you'd need to do is teach the program the sub level system and you'd be off. Why store long strings?

Despite the fact that periodic tables for the TI-85 exist, I still use paper ones. Why? Because I am fanatical about precision, and only the paper tables I have give me masses down to 7 or more decimal places.

Well, I think it is possible to put it down to 7 decimal digits, but I don't have a periodic table, I found a "digital" copy on a very nice web site, with all the information you'd need about the elements. The problem is, a Periodic Table program won't stay long on someone's calc if its too big... especially w/82/3... I can see on the 86, but not 82/3/5.. I'd say maximum size should be 7000 bytes.

And you need this excessive precision for what?
