I would recommend that you find words, phrases, numbers that mean something to you and use those in your memorization techniques. My examples are definitely geared to me and my experiences or thought processes, but hopefully they can guide you toward memorizing your own way. FYI, our values may be different from your book, these are the ones our college chose for us to memorize. Here we go................ Sodium...So Dumb....I think of that "almost politically correct" redneck by the red truck and guess he's around 135-145lbs. Potassium (K+ age of kids going into Pre-K....3.5-5.0 years old) These may not be right, but idk, so it works for me. Chloride (LORD I'D....95 sure sounds great...but Lord I've love to see 108 "one O eight") Magnesium....(Magneto was in school of mutants with Xavier from middle school to just out of college so 12-26 [1.2-2.6]. But they honed their skills before graduation in years 16-25. 1.6-2.5) AGAIN...keep in mind, my numbers may not match yours, it depends on the school. Hco3..bicarb (bike hard....if you're familiar with cycling, you know that you must BIKE HARD to average 22-26mph. Another is BIG CAR....22-26 inch rims) I knew a guy in jr high with a full mustache and could've grown a beard, so I remembered HGB..(He Grew a Beard between 12-18....jr high through sr high.) These are just numerous ways I memorized the values. Hopefully they are helpful, but ultimately, you have to make the values fit something familiar to you personally. Best wishes!!
