http://en.wikipedia.org/wiki/Dmitri_Mendeleev
Dmitri Mendeleev is generally credited with devising the Periodic Table in
1869.

"In 1863 there were 56 known elements with a new element being discovered at
a rate of approximately one per year.

Other scientists had previously identified periodicity of elements. John
Newlands described a Law of Octaves, noting their periodicity according to
relative atomic weight in 1864, publishing it in 1865. His proposal
identified the potential for new elements such as germanium. The concept was
criticized and his innovation was not recognized by the Society of Chemists
until 1887. Another person to prose a periodic table was Lothar Meyer, who
published a paper in 1864 describing 28 elements classified by their
valence, but with no prediction of new elements. Meyer, who is often
credited with the discovery of the periodic system, opposed and criticized
the Periodic Law."

http://en.wikipedia.org/wiki/Henry_Moseley
"In 1913, Moseley observed and measured the X-ray spectra of various
chemical elements.
Moseley's law in X-ray spectra justified many concepts in chemistry
by sorting the chemical elements of the periodic table
of the elements in a quite logical order based on their physics."

Niels Bohr's published in a series of three papers in the summer and fall of
1913.

The fact of the matter is that
the Periodic Table is arranged
based on protons in nuclei,
and not on electron orbits.

It is sad that many science web site authors
are ignorant
or have a race/religion/nationality bias.

http://en.wikipedia.org/wiki/Periodic_table

"The periodic table is a tabular arrangement of the chemical elements,
organized on the basis of their atomic numbers.."

http://en.wikipedia.org/wiki/Atomic_number

"In chemistry and physics,
the atomic number (also known as the proton number)
is the number of protons found in the nucleus of an atom.."

As can be seen,
the Physics Today article
was just another effort by the Khazar Gang
to claim credit for the works of others.
