Revamping The Periodic Table? 472
vinohradska writes "There is an interesting article on the periodic table over at Slate: 'Oxford ecologist Philip Stewart has designed a new periodic table of the elements, and it's a hit. American schools are placing orders daily for Stewart's table, and the Royal Society of Chemists recently sent a copy to every British secondary school. Stewart's is the only remake to achieve widespread adoption since Dmitri Mendeleev invented the original periodic table in a fit of brilliance in 1869.' "

Frankly, I liked the 1950s chart after it better. There was a certain beauty in the layout of that chart. The new chart is pretty much just the elements spiraled across a picture of a galaxy.

2) On a positive note, I believe that the visual upgrades to the chart (although, will color blind people have any issues getting the full content from the chart now?) will definitely help students remember and learn emelents easier. The visual separation should definitely increase the ability for students to remember how many different colors, how many elemnts per color per spiral, etc. 3) What I think is the most interesting point of all of this is the relation of the elements being able to be tied back together and done so in a shape that mirrors the overall shape of the galaxy. It's sort of like the movie "Pi" where we can see trends, shapes, circles and spirals all within our life and this would be just one more example.

But above it all I prefer the current table by far.

Still and all, I will probably have it only as a demo tool. The standard chart is much easier to read. It also shows electron configurations more clearly than the spiral does.

A few years later I saw a list of known isotopes arranged one element per line and indented based on the weight of the nucleus, with simple hydrogen in the eupper-left corner. The stable isotopes were colored differently, and the color band formed a skewed triangle that would have also wrapped nicely around a cone.

The screen showed a central nucleus, with spinning electron holes. Your job was to capture free electrons with your little ship and shoot them into the holes. You started with the first shell with 2 holes, one for H and one for He, and then the next shell of 8 appeared for you to fill, etc. etc. Eventually the screen got very cramped, which must be why they stopped at 54.
If you fired the electron and missed the hole, you'd hit the nucleus, and the whole thing would explode. Very frustrating once you had made it all the way to Germainium (I remember playing this game about the same time as the Jackson's Victory Tour, and being tickled that there was an element named Germainium, but I digress).

The periodic table is a kind of model, and like all models, it's just one way of simplifying the real world and diagraming it for easy understanding by humans. There's no reason everyone should use one model of anything for all purposes, and if this new "galaxy" chart helps middle school kids learn and understand chemistry before moving on to the "standard" periodic table, it's a good thing.

But as for the galaxy graphics, well, he's just trying to make it pretty (read: this is why people are buying it. It's pretty.) And as for the spiral shape, well, all it does is put Ne next to Na, Ar next to K, Kr next to RB, etc. Which does make sense, as they differ by only one electron and one proton. (We'll ignore neutrons for now.)
But beyond that, it's just a novelty, and I don't see it replacing the traditional period chart of the elements.
And as for neutronium, yes, it gives a convenient place for it, but I'm not sure it even belongs there. I wouldn't call it an atom [answers.com] because it doesn't meet definition 3a, so I wouldn't call it an element at all. So I wouldn't put it on the periodic chart of the elements ...

I like the old chart because all of the detail is right there with the element -- I don't have to go and look at the chart along the right side of the page to get all of its details. But
Yes, the whole 'galaxy' thing is most likely to get children interested in science. They'd have probably worked a dinosaur in there, too, if someone hadn't pointed out that it'd then be sexist, and appeal to boys more than girls, but if it gets the kids interested, and maybe they then move to what we think of as the 'normal' periodic table (being that it's much more dense with its information), it doesn't really hurt anyone.
It just makes it so that the kids won't get jokes like the Periodic Table of Condiments [backtable.org] quite as quickly. (of course, the folks who made it didn't understand the Periodic Table of Elements, or they'd have placed similarly behaving items in a column, with the most reactive elements towards the edges, except for the far right column for things that never go bad)

I always thought of the (current) periodic table to be a non-obvious hack at organizing this information. Sure, it's logical in a sort of kinda sorta way. I believe we become comfortable with it because it is what we are taught, but I do not see how the current design conveys the benefits you suggest it does.
Please expand on your 3 points because they really don't make sense to me.
How is the existing periodic table not a gross oversimplification if this new one is?
As far as I can tell, the new one(s) are entirely complete and accurate. Moreso, they actually are organized in a way that can be extended. The existing periodic table is only complete because of the footnotes, extensions and other non-obvious changes required to stuff all of that extra didn't-know-it-existed-at-the-time information into it.
The new one isn't only pretty, it's totally logical in an absolutely obvious way.
Maybe you have to _not_ be a scientist to see it, I don't know.

I would suggest that teaching students yet another way to memorize information without learning the how or why is not a good thing.
Secondly, the periodic table already separates the elements into s, p, d and f blocks according to (most) of their relevant properties, and since this chart is largely just a pretty way of re-drawing the information there is not much to be gained. I have colour-coded periodic tables available as well.
Thirdly, as another poster has pointed out, the electronegativity trend is not quite as obvious according to this layout; as well, other trends such as EA and the preferred ion charges are harder to assess. To return to the learning aspect, I would argue that the order of the current periodic table is the easier way for a student to assess these properties and understand, at least at some level, why they arise.
I'm not beating my CRC here and resisting change because I am scared, but I think this is change for the sake of change and marketing.
Cheers!

1. What seperates diffrent elements in number of protons

4. Common physical charecteristics.
Number 2 is my argument of why there is a 'footnote' in the periodic table. the first 2 columns are s orbitals the ones in the middle Sc-Zn are d orbitals and on the other side is p orbitals starting with B-NE. The footnote is f orbitals. Now please dont start the argument, well if that is the case then He should be in column 2. Alot of Chem programs do this weird thing where He is produced twice on the periodic table once above colomn 2 and in its usual place.
As for the new layout it dystroys this simple oh what orbital is being filled layout. as well as for the life of me I cant figure out why H, He, Be, and Li are on the same rung.

Although, perhaps I could tear this 'new version' to peices even better if there were a version I could actually SEE posted somewhere on the net. There are fuzzy low-res versions all over the place, but not a one that I can really study.
There are DOZENs if not HUNDREDS of different table formats. I doubt that this one is even moderatly new, excepting perhaps the irrelevant backdrop. The layout depends on what is of interest; a astrophysics professor might have one that accentuates the electron energy states, whereas a chemical engineer might have a chart which accentuates the prevailence of an element in nature.
The current form is incredibly logical. Purly logical. Proton count increases from top-left to bottom right. Happens to correspond to about a half dozen different patterns. God, I can't even think of all the variables that our simple, standard table shows. There is SO much information packed into it. Even if you stripped out everything but the symbol the current table would convey a staggering amount of information. This new table? Mmmm.... not so much.
As for your last comment: It *IS* worse. Because eventually it will have to be discarded and students will have to learn to use the 'normal' periodic table. Sure it will be easier than if they had never heard of elements and protons etc before, but they won't be familiar with it. They will be slower with its use, and more easily frustrated. And public schools are famous for leaving out details that a teacher 'doesn't feel is important'. I tutored college chemistry: anything which adds to confusion without benifit is very bad. There is just too much new information to convey in a short time to have to add yet something else.
All of that said, I read the article hoping to find something which IS better and more intuitive. I believe one could be made which would be better suited to 'general use'; e.g. the casual chemist: the engineer type that looks to a table once in a while to calculate combustion energies, or for the student of general inorganic chemistry. Was bummed to see that POS.
