Do you have some sites with 3D representations of the periodic table ??? (A bit like visual elements, see above) !! I love the idea of representing the table as a landscape, a Periodic World !! For me, it's my dreamworld ! I know every spot and I can travel from element to element. You have the desert of metals with mostley metallic looks, but you also have the beautiful countries of the non-metals. You have the province of the alkalimetals, where you could better hide is it rains. Somwhere in the south you have an island with the more exotic metals, but watch out where you go, cause you could come in regions that could kill you in a few seconds because of their reactivity. I LOVE to travel in the fantastic world of the elements. Most people don't understand me, but for me it's paradise !!! (Peter Atkins, prof. chemistry in Oxford I think, has written a great book about his trip in this world, 'The periodic kingdom of the elements' ... it's my favourite chemistry book. I read it almost 15 times, again and again, and again :) ) So if anyone has some sites about this subject, please let me know. Thanx

I like the link to periodic table pages!

 

A lot of amazing things are happening in science. This story is about one man re-inventing the periodic table so that it is easy to understand. Imagine that!

 

The fact that someone would dare change the periodic table suggests more great things are about to happen in the world of science. It is revolutionary because its radical new design tears down the current ideas and starts again from scratch.

 

You can decide for yourself if this man has made the periodic table easy to understand - simply go to http://www.rotaperiod.com/

 

Highlights:

 

- It uses 12 columns instead of 18

 

- It re-draws the line between metals and non-metals

 

- It emphasizes the strength of the 4+ elements (temperature, organic chemistry)

 

- It does not classify the 5+, 6+, 7+, 8+ metals into groups V, VI, VII, and VIII (or IUPAC 5, 6, 7, 8)

 

- It uses the vertical and horizontal of the page to displace elements in a new way

 

- It incorporates the Lanthanide and Actinide Series elements

 

It is called the Rota Period (or Rota's Period) and makes Chemistry easier to understand because it is based upon showing valence/oxidation (which determine how elements combine).

Since many elements show multiple oxidation states the table is ambiguous. If it's meant to me highest oxidation states then copper is wrong; if it's meant to be most common then iron is wrong. If the asignment is arbitrary then it's all wrong.

It also fails to convey any information about the underlying reason for the periodic nature. It springs from the arangement of the electrons in what for simplicity's sake are usually called shells.

I have to agree also, with the addition that the time taken to learn/understand yours, coupled with the time to Unlearn and then Relearn the correct one would be unwise.

 

better to learn the correct Table First and have it explained Well, than risk later confusion.

 

don`t get me wrong, I have done similar things with the table myself as purely excersize and fun, and there is some merit in your version, but I can`t think of ANY way to really improve the existing Table.

there are other representations of the table to focus on specific properties but the standard table is IMHO the best at describing lots of trends, arrangements and properties all at once. sticking with the standard table would definitely be best for general high school level chemistry.

It seems that helium should be with hydrogen at the head of the periodic table because they are both of s type mode. This was showed since seventy years by Bohr, Pauli and others, but the chemists have not yet accepted it. They say that the periodic table should be based on chemical properties and not on quantum mechanics, an absurd or at least incomprehensible theory. Helium is usually falsely placed with the other rare gases which are of p type mode.

If the Periodic Table was like an "alphabet" of molecular structure... has anyone ever made a "dictionary" of molecules?

 

Would it even be possible to list all the known molecules and their properties in a single reference material, or are there just too many?

well there are 6.6 billion molecules of DNA each of which would take a good chunk of a library to write out. then theres the rest of the organic molecules. proteins have really long chemical formulae and viruses.

 

it will be possible when we have denser digital data storage and 1 exabyte is relatively cheap.
