h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

So far, I like what I'm seeing.

After you chemists get all the facts right, it'll be great to have this info in the guide.

Would it be too much to add a small tribute to the discovery of how the elements seem to fall into groups and the beginnings of the table and how it led to the prediction of finding certain elements.

Also, re the discussion of solubility in water, I thought it was somewhat hard to say whether ethanol disolves in water or water disolves in ethanol. I rather enjoy the fact that the result of that solution has less volume than the sum of the two separate compounds.

I placed links to pages at the bottom - like [URL removed by moderator]- there you can read stuff about 115.

Hey BARTON, imagine how glad I am to see you here...

Cheers,

HELL

Oh by the way Barton about the history... Check out the peer review (I have added somethings)

This looks like an excellent entry. I also note that you have a few more articles on the same sort of subject... history of the table, a bio of Mendeleev... have you considered doing this as a University project, as opposed to putting them through Peer Review? You get a bit more prestige and recognition through the University, and you don't have to wait through the queue. Check this out for more info: http://www.bbc.co.uk/h2g2/guide/C573

I know the University... I did not like the concept. For me it was easier to do it that way.

Maybe I'll learn more about University projects.

Anyhow, I wanted everyone to look at this work and not just people interested in chemistry. Maybe that was the main reason i put it in the PR and not in the Uni.

And recognition and awards and all that stuff... Who needs that?

Cheerio, Glad y'all liked the entries. There's more in my drawer just wait . Hehehe

HELL

Well, I figured you already knew the upside of PR, which is, obviously, the feedback. In that case, I wish you well with this piece here, as I've already registered my opinion, and I suppose I'll have to go check out some of the others...

I noticed the history right after I posted the last. I'll read it as soon as I can find a spare minute.

Personally I really like this entry, I mightent be a chemist, but it seems quite complete.

Just one format point, in the tables I would put the name of the element in bold to help it stand out from the atomic numbers.

Just a thought.

Researcher PSG

p.s. If I where you I'd look at the university area, as you seem to have enough specialist knowledge to set up an project on, say, an introduction to chemistry, as a series of jumping off points for beginners to more detailed entries.
Just a thought.

I have added some bits about the amu (atomic mass unit) and isotopes and metals and gases and all. I did not want to go in depth, because... Well maybe there's something to say about each and every one of those elements, and more information should be found there if there is need for that kind of info anyway (I mean I would not want to include ALL ionic radii and 1st and 2nd and higher order ionization energies and nuclear spins of all isotopes...)

About the NaBr Example part: Orcus found it irritating, that I have formulated that ions are well soluble in water... well I said *element* ions are well soluble in water, not just any ion. Of course it is right to state that the hydration energy must overcome the crystallisation energy, and most of the times it's the entropy that does the dirty work and not the enthalpy (Dissolving NaCl in soup actually makes the soup COLDER)... I'm working on a better example, but I don't think this one is *that* inaccurate.

HELL

Hello again Hell, got another wee problem

Other properties of the elements section seems to forget (quite understandably) Hydrogen. It is gaseous at room temperature, and not metallic. Problem is of course is that it doesnt really belong in the first group and can sometimes be found floating somewhere above the "inert" gases at the top of group 18.

Probably best to not go into too much detail about H though, but I do think some sort of inclusion in gases and metals section is warranted.

Of course you are right vp. Hydrogen included.

Thank you,

HELL

PTE was replaced by 'periodic table'

Of course it is a lot better that way.

Thank you all,

HELL

Congratulations! This entry is recommended for inclusion in the Edited Guide. Thanks for making such a valuable contribution to the Guide.

Yipiiiieeee!

Well done, Hell!

Yey , well done hell

Congratulations!

it certainly got so many of us talking
