Excerpt: Mendeleyev's Dream
On its 150th anniversary, a chemist looks back at the various tables we almost ended up with.
That's some heavy stuff
This interactive periodic table is one of our favorite toys on the Internet this week
The periodic table gets a few tweaks.
Researchers confirm the existence of this synthetic element in a new accelerator study. Will it be enough to give ununpentium official recognition and a new name?
The science of how much we suck
How scientists create superheavy atoms.
The claim needs to be verified by chemical authorities, but the team says it's the strongest evidence yet for the highly unstable element.
PopSci discovers the elements, one by one
Depending on who you ask, these long-ignored, widely-scattered elements are either a dealbreaker or no problem at all
The planet has limited resources of several important elements, many of which can do what no other element can. Here's what's left of the periodic table, and what would happen if we run out
Long hoped to represent the point where superheavy elements don't immediately decay, Ununquadium turns out to be not so stable after all
Element naming has a surprisingly contentious history. Bitterly contentious. We spoke to Sigurd Hofmann, credited recently with the discovery of element 112, to see how he might change course
The chemistry cornerstone celebrates its 140th birthday
Our mad scientist has expanded his periodic-table product empire
