Holmium Memes

It's a chemistry Christmas tree! This brilliant orbital diagram is arranged to look like a festive tree, with electron configurations forming the perfect holiday shape. The title "Holmium, Holmium, Holmium!" is a nerdy chemistry pun on "Ho, Ho, Ho!" since Holmium's chemical symbol is Ho. The star on top is the 1s² orbital—where all electron configurations begin—while the ornaments are the various s, p, d, and f orbitals filling up according to the Aufbau principle. Chemistry teachers everywhere are printing this for their classroom doors right now!

Only chemistry nerds would recognize that "HHoHeSn" is actually the chemical symbols for Hydrogen (H), Holmium (Ho), Helium (He), and Tin (Sn) strung together. It's the perfect password—uncrackable to normal people but painfully obvious to anyone who's ever had to memorize the periodic table. Next time someone asks why my Wi-Fi is named "NaBrO," I'll just smile knowingly and walk away.
