This is moderately weird: it's a periodic table of atheists, and I've been assigned an atomic number of 4, which makes me a rare, brittle, and highly toxic metal with a high melting point. Does anyone else look at these charts and try to draw inferences from chemical properties to the individual?

Element: Ytterbium (Yb)
Atomic Number: 70
Mass: Seven "stable" isotopes, from 168 to 176 amu. Two of those are nominally radioactive, with half-lives vastly in excess of the age of the universe.
Laser cooling wavelength: 399 nm and 556 nm.
Doppler cooling limit: 690 μK in the UV and 4.4 μK in the…
Element: Rubidium (Rb)
Atomic Number: 37
Mass: two "stable" isotopes, 85 and 87 amu (rubidium-87 is technically radioactive, but it's half-life is 48 billion years, so it might as well be stable for atomic physics purposes.
Laser cooling wavelength: 780 nm
Doppler cooling limit: 140 μK

A number of SF-related sites have been talking about the "Periodic Table of Women in SF" put together by Sandra McDonald, presumably passed around at Wiscon. James Nicoll has a list of the authors, and SFSignal has a link to the table, which I will reproduce here to save you the annoyance of…
Element: Strontium (Sr)
Atomic Number: 38
Mass: Four stable isotopes, ranging from 84 to 88 amu
Laser cooling wavelength: Two different transitions are used in the laser cooling of strontium: a blue line at 461 nm that's an ordinary sort of transition, and an exceptionally narrow "intercombination…
