Periodic Table of Elements To Get an Update
Lazarian writes "Scientists from around the world have put forth an update to the Periodic Table of Elements. In particular, they are changing the manner in which atomic weights of ten elements are expressed. From the article: 'For example, sulfur is commonly known to have a standard atomic weight of 32.065. However, its actual atomic weight can be anywhere between 32.059 and 32.076, depending on where the element is found.'"
Again?.
To summarise the summary of the summary: people are a problem. ~ h2g2
not really, if it's a problem now, it was then too since these weights didn't magically change. Really, it doesn't terribly matter much as it is, the discrepancy is tiny and for most molecules, largely irrelevant. For any calculation that really reall matters, you won't be using the range on the table, you'd be measuring the isotope ratio in your sample and for times when it doesn't, well, that's self explanatory.

While we're at it, maybe this is a good time for you colonials to finally learn how to spell?

Just as soon as you guys learn how to cook.
Faster! Faster! Faster would be better!
Re:Aluminium. Sulphur.

Okay, I'll feed the troll.
The name originates from the Latin word 'sulfur' and Middle English 'sulfre' meaning brimstone. [cite]
On the other hand, the other word is a bit more blurry as to who "wins"
...In 1807, Davy proposed the name alumium for the metal, undiscovered at that time, and later agreed to change it to aluminum.
Shortly thereafter, the name aluminium was adopted by IUPAC to conform with the "ium" ending of most elements. Aluminium is the IUPAC spelling and therefore the international standard.
Aluminium was also the accepted spelling in the U.S.A. until 1925, at which time the American Chemical Society decided to revert back to aluminum, and to this day Americans still refer to aluminium as "aluminum".

I only post comments when someone on the internet is wrong.
Well, England were on for a whitewash but Australia seem to have made a sudden comeback and we may have a real fight on our hands for the Ashes after all.
One gripe I have about the IUPAC's insistence on -ium for aluminium is that they break that convention for elements like tantalum, platinum, molybdenum, and lanthanum. Y'know, if they really, REALLY wanted to be consistent, they'd rename those tantalium, platinium, molybdenium, and lanthanium.
Of course, I can't complain too hard, as the ACS used "aluminium" until they changed their minds...
