Electron orbitals Memes

This is what happens when chemistry teachers get into the holiday spirit! The left side shows electron orbital configurations arranged in a Christmas tree shape, complete with those s, p, d, and f subshells branching out like pine needles. But the real gift is on the right—chemical elements spelling out "MERRY CHRISTMAS" using their symbols! Manganese (Mn), Erbium (Er), Rhodium (Rh), Radium (Ra), Yttrium (Y) for "MERRY" and Carbon (C), Hydrogen (H), Rhodium (Rh), Iodine (I), Sulfur (S), Thulium (Tm), Arsenic (As) for "CHRISTMAS." The little lab equipment at the bottom is basically the chemistry equivalent of a tree stand. Whoever made this deserves extra credit and probably has students who actually look forward to the periodic table quiz!
