You know the periodic table
that hung on the wall of every science class you took at school? As of today, it’s wrong. Or more precisely, it's inaccurate.

One of the biggest changes in decades is set to be made to the periodic table, with the atomic weight of 10 elements altered to better reflect how they occur in nature.

The periodic tale of the elements has been around a LONG time. It makes sense that our first conceptions about the elements would be wrong. Since technology has improved over the last few decades, I can see where things might need to be updated.

Actually there is nothing "wrong" with the Periodic Table as it presently exists.......it was established in the manner that it is in order to compare elemental states at as closely as possible to common abilities to react with other elements/compounds. New elements have been added on a more or less continuous basis over the past century, however they must meet a specific set of standards in order to be included. There is a SPECIFIC reason for excluding isotopic ranges........they simply do not react in common terms with other elements, hell, some have a "half-life" of only seconds, if that much.

Further, it is not as though we have not known about isotopic forms of various elements for decades, if not centuries. Whether they exist in nature is irrelevant.......

Reading the article (and reading between the lines) it appears that this effort is the result of someone attempting to use the data on the table under some archaic rules of evidence in court cases involving the chemistry surrounding human drug analysis. The Periodic Table is a teaching aid, not a "courtroom prop". and it really pisses me off when groups attempt to alter the realities of scientific fact to suit some other agenda.

This is "slow news day" hogwash........

Is there a really such a thing as a scientific "FACT" for anything???

Completly agree with all the other stuff you said about these others co-opting the periodic table

When it comes to the atomic structure of elements in the periodic table certainly yes.......We can now actually see their atomic structure under a SEM/MRM, where in the past their structure could be only calculated.

On edit:  Sorry for the acronym.....

SEM = Scanning Electron Microscope
MRM = Magnetic Resonance Microscope

Not even close.  Everything, instead of anything would have been a better choice of words

But more to the point......is there a difference between the southern kingfish, whiting, Virginia hardheads and sea mullet? Just because you aren't doing drugs, under/over educated white, indian chinese, corn fed tea party christian domestic terrorist patriot. This all explains why down is up, up is down, cats fornicating with beetles. Speaking of which I have owned a volswagon.

Thats okay.  I use a Pertometer just about everyday with a 2µm radius tip.  I know not even close to the same scale as those, but I did know what they were.

Where is the equation that undermines Schrödinger's Equation? Other than that, of course isotopes exist in state as TVDOC said. The periodic table is supposed to be a vague guideline not a final word on the composition of matter at all times.
