Colorful elements Memes

This is pure periodic table humor at its finest! The meme contrasts different architectural styles with metal elements: On top, we've got the drab, gray building labeled "Every single metal element" (looking about as exciting as a lecture on electron configurations) next to the flamboyant pink and purple house labeled "Copper and gold" - which actually do have those distinctive colorful properties in their pure forms. Then there's bismuth at the bottom, showing a house with rainbow Christmas lights. This is chemistry gold (pun intended) because bismuth crystals naturally form those mind-blowing rainbow-colored geometric structures due to oxide layers creating thin-film interference. It's basically nature's own psychedelic light show! The title "100% Fr" is the cherry on top - Fr being francium, one of the rarest naturally occurring elements. So this meme is indeed 100% rare elemental humor!
