Mnemonic Sentences
A common way to memorize an ordered sequence, such as the elements in the periodic table, is to create a mnemonic sentence. A mnemonic takes the initial letters from each sequence item and inserts other words that begin with that same letter to create a silly sentence. For instance, the sentence "New Nation Might Also Sign Peace Security Clause" is a mnemonic for elements 10-17, whose symbols are: Ne, Na, Mg, Al, Si, P, S, Cl. Although mnemonic sentences are often nonsensical, they are easier to recall than the lists they replace. Create your own mnemonics with vivid visuals and words that you will likely remember. Have a mnemonic contest among your study group, and pick the best sentences.
Element Flashcards
Use flashcards to memorize large quantities of information. Target your flashcard design toward the aspect of the periodic table you want to memorize most. For instance, if you are working on remembering the symbol for each element, write the symbol on one side and the name of the element on the reverse. Drill yourself and challenge your peers to a competition with your element flashcards. Work through all the cards, removing the ones you get correct and reshuffling your mistakes to practice again. Practice using both the back and the front side of the flashcards.
Chemistry Songs
Employ rhythm and melody as memory tools by setting the periodic table to music. Tom Lehrer's song "The Elements" includes most elements of the periodic table, in a scattered order that fits well to music. Other chemistry songs tackle the elements in order, focus on specific groups of elements or include general information about the periodic table. Or, create your own element memorization song.
Chemistry Quizzes
Matching games, multiple-choice and fill-in-the-blank questions can help prepare you for future tests. Online chemistry resources offer quiz games based on chemical symbols, names or properties. Or, make your own quizzes using notebook paper. Crease the paper down the middle to create two sides. On the left, write the element name or symbol. On the right, across from the name, write facts about the element that you want to memorize, such as "Reacts explosively with water" or "Located in the second row." Fold the paper so you can only see one side to quiz yourself on the element's identity.
