Use element atomic numbers and symbols to decode 24 words associated with Valentine’s Day, such as Flowers, Be Mine, Cupids, etc.

Two versions are provided – they have the same 24 words, but one is decorated with pictures that relate to the words and the other isn’t. (We find older students are quick to use the pictures instead of the periodic table, which is why we provide the version that has no pictures.)
