How to memorize the whole periodic table

elephant.jpgJust as some math geeks strive to memorize pi to 1,000 places (or in the case of British savant and mental_floss bloggee Daniel Tammet, several thousand places), there are science geeks who strive to memorize the periodic table. (Granted, the periodic table has a finite amount of information, whereas pi does not. But still, it’s a daunting task.) To help get your keyboards sharpened for our periodic table quiz later this week, here are some tips on how you can commit the whole shebang to memory (and thus pass with flying colors):

• Of course, long mnemonic sentences can help you remember the names of the elements, like Hi! He Lies Because Boron CanNot Oxide Fluoride (for the first nine elements H, He, Li, Be, Bo, C, N, O and F) or New Nation Might Also Sign Peace Security Clause for the eight elements following.
• What’s harder is memorizing the other periodic table data, like the elements’ number, valence, mass etc. But thememorypage.net has a cool method for remembering long strings of numbers, by converting them to words, which you can then string together into sentences! Check it out:

Suppose we assigned each of the digits 0 through 9 to a consonant. Then, when we want to remember a number, we convert the number into consonants, insert vowels, and form a word. This word can then be used to form an association much more readily, rather than trying to use the number itself.

As an example, suppose we want to remember that the Old Testament has 39 books, and suppose 3 and 9 translated into M and P, respectively. We could then insert the vowel A between the consonants to come up with the word “map”. We would then visualize a huge map in front of us, with the Mediterranean Sea, Israel, Egypt, Mt. Sinai, etc.: a nice map of the Old Testament. Two weeks later we want to remember how many books were in the Old Testament. We recall that huge map with all the places on it. MAP… consonants are M and P… that’s 3 and 9. 39! We did it! That’s sort of a roundabout way of doing it, but it works, because of the associations.

Now that you’ve got that down, study up and get ready for our upcoming quiz! (Oh, and don’t forget to study the history and fun trivia behind all those elements either; that’ll definitely come in handy.)

  1. I actually had to memorize the periodic table (symbols at least) for an Inorganic Chemistry class, a junior-level class for the BS Chemistry degree. The first day of class, the professor informed us that 20% of the final exam would be to fill in a blank periodic table. It sounded terrifying, but by the end of the semester, it was the easiest 20 points I ever got on a final exam.

  2. or you could learn Tom Lehrer’s song “The Elements”…

  3. When I was in high school my science teacher started of by saying that the periodic table was put together by two russian scientists.
    H. Helibebcnof and Nena Mgalsipsclarkca
    So everyone memorised these two names and later on in the class he pointed out that these two names were actually the first 20 elements, making remembering them that much easier.

    15 years later an I can still rattle them off if need be.

  4. ok - i remember i have a bulk of it memorized when i took organic chem in college - however i have since forgotten most of the locations.
    i did find the best web site i wish i had in college for the table…
    i do nothing with chemistry today - and it is still one of my favorites
    ——-

  5. touchspin.com/chem/DisplayTable.html

  6. I had to memorize Lehrer’s “The Elements.” It wasn’t too bad. Although with that song you don’t learn their order, number, or even anything discovered after 1963….

  7. Or you could just… Damn, I was about to say Tom Lehrer’s ‘Element Song’ too. I learned it in 8th grade and I can still sing it. It really is useful, unless your trying to recall the the elements that begin with ytt.. and so on. Shout out to Ransom!
