The Modern Triumph of the Periodic Table of Elements

I was disappointed by this article because it has almost nothing to do with the "Periodic Table of Elements," just the elements themselves -- as if we're supposed to be surprised by the fact that elements are in things.

The article also presents the number of elements in things as if that can show some kind of quantifiable change in a positive or negative way (for example, they call out the number of elements in a cell phone as having increased since the first cell phone).

I was hoping for something a bit more insightful about the design of the periodic table itself, whether about

1. Increasing order by atomic mass (and the ramifications thereof)

2. Arrangement of periods and the predictions we've been able to make/use

3. The groups of the table and the predictions we've been able to make/use, though I guess this is most common among the noble gases

4. Rare earth metals

And I'm sure there's a lot more I don't know -- every time I learn something about the periodic table, the more impressed I am by how orderly and patterned it is today despite having been initially designed (with gaps!) a century and a half ago.

The article could even have gone into how there are spoofs of the periodic table just because it's such a lasting, easily-understandable design.

It's a nice figure displaying the presence of elements in the Earth core, human body and cell phones, but why does it give no hydrogen in cell phones? Also the picture of "native gold" is really pyrite, also known as fool's gold. My confidence levels for this article are low.
