How to play the chemical elements number game
Chemical elements are the cards, each with its symbol printed below the name, and the aim is to order them by atomic number, lowest first. You start with one element on the line and its atomic number showing. Every new card goes above or below the elements already there, into the gap you pick. A correct pick reveals the atomic number; an incorrect one still files the element in its true place and costs one of three lives.
The deck runs across the whole periodic table, from the lightest gases to synthetic heavyweights made in labs. If you can picture the rows of the table, you're in good shape, but the long middle stretch of transition metals and the rare earths is a maze. Some symbols come from older names that don't match the English one, so the name is usually the better clue. Neighbors in this deck often sit very close together.
