I like it, do you think you could use frames for the bottom though? So that when you click on an element, the entire page doesn't have to load again?

Just a small detail though.

I like your list of constants.

Thank you for comments!
Frames are not good for indexing by search engines :)
I've just added more data about each element!

Sigh...sign of my age. When I was in school, only 106 elements were known, and IIRC, elements 105 and 106 were given the generic nomenclature "Unilpentium" and "Unilhexium" respectively.

Graar! I don't mean to nitpick but Sc,Y,La,Ac,An,Cd,Hg and Uub aren't transition metals iirc.

Cd, Hg

Graar! I don't mean to nitpick but Sc,Y,La,Ac,An,Cd,Hg and Uub aren't transition metals iirc.

Well, I will respectfully disagree with the last statement.
Here is the link http://en.wikipedia.org/wiki/Transition_metal
Or (from http://en.wikipedia.org/wiki/Cadmium)
Cadmium is a chemical element in the periodic table that has the symbol Cd and atomic number 48. A relatively rare, soft, bluish-white, toxic transition metal, cadmium occurs with zinc ores and is used largely in batteries.

iirc the definition of a transition metal element is a d-block element which forms ions with at least one unpaired d-block electron still present. The ones I listed above don't do this (at least, not for stable compounds iirc).

oh, and on that first like you posted

By this definition, zinc, cadmium, and mercury are excluded from the transition metals, as they have a d10 configuration

transition metals

OK, I see that people define it differently.

In chemistry, the term transition metal (sometimes also called a transition element) has two possible meanings:

* It commonly refers to any element in the d-block of the periodic table, including zinc, cadmium and mercury. This corresponds to groups 3 to 12 on the periodic table.

* More strictly, IUPAC defines the transition metals as any element with an incomplete d subshell or that may form stable ions only with an incomplete d subshell (IUPAC definition: "An element whose atom has an incomplete d sub-shell, or which can give rise to cations with an incomplete d sub-shell."). By this definition, zinc, cadmium, and mercury are excluded from the transition metals, as they have a d10 configuration. Only a few transient species of these elements that leave ions with a partly filled d subshell have been formed, and mercury(I) only occurs as Hg22+, which does not strictly form a lone ion with a partly filled subshell, and hence these three elements are inconsistent with the latter definition.[1] They do form ions with a 2+ oxidation state, but these retain the 4d10 configuration. Element 112 may also be excluded although its oxidation properties are unlikely to be observed due to its radioactive nature. This definition includes groups 3 to 11 on the periodic table.

ONLINE TOOLS for chemists

Please check my site again!
I've added a "ONLINE TOOLS" with
molar mass calculator and chemical equation balancer!

I've just added NEWS section there where I present collected news from several sources.
Do you think it can be useful?
Thank you!

It is definitely somewhere I would think of going if I was still in my ap chem class (you're a little late). But I like it, and I'm sure that you will tweak the design as the site progresses.

...and please, don't put any frames...its fine the way it is. Actually, although I wouldn't use frames, the way you view the elements now does feel a little awkward.
