A Chemistry Christmas Carol Apologies to Charles Dickens How many times are elements mentioned in this story excerpt? Meanwhile, in a stockroom, poor Rubidium Cratchet, the lab technitium, was washing dishes in ice cold water. Ebenezer only allowed him one piece of carbon paper for all the lab reports and one small candle to aluminum. A graduate of Berkelium College in Californium, Rub was no Einsteinium, but he wasn't so-dium, either. He did tend right to bismuth on time. It was six o'clock on Christmas Eve, and Rub asked to go holmium early. "You've got a lot of gallium," replied Ebenezer. "I'll be francium, but fermium. Hafnium a day's work, halfnium a day's pay."

Chemistry Carols Test Tubes Bubbling (to the tune of Chestnuts Roasting on an Open Fire) Test tubes bubbling in a water bath Strong smells nipping at your nose. Tiny molecules with their atoms all aglow Will find it hard to be inert tonight. They know that Chlorine's on its way He's loaded lots of little electrons on his sleigh And every student's slide rule is on the sly To see if the teacher really can multiply. And so I offer you this simple phrase To chemistry students in this room Although it's been said many times, many ways Merry molecules to you. American Chemical Society 25
