I need help memorizing all the compounds in chemistry and their names at least the most common ones. I compete in UIL science and I need to memorize facts in Biology that I keep forgetting. I compete in UIL science and I’m only good at physics. I always forget the biology and chemistry because I see it has to do more with memorization then physics at least thats how I see it not how it might actually be. I see a lot of potential in using memory techniques to memorize book loads of biology facts and the names and corresponding symbols of compounds and their reactions. I’m reading a book by Dominic O’ Brien called YOU CAN HAVE AN AMAZING MEMORY. However, I need to know how to apply this things to what I want to learn. Also does any one know how this could be applied to martial arts and to learning songs in portugese for caporeira. I’m more interested in the science part because I only have a little more then month to accomplish the memorization of the biology and chemistry. Please I need help?
What I would do. Start here:
http://quizlet.com/subject/compounds/
Now the names can be broken down into their respective parts:
ammonium nitrate = NH₄NO₃
beryllium nitrate = Be(NO₃)₂
iron(III) nitrate = Fe(NO₃)₃
lead(II) nitrate = Pb(NO₃)₂
magnesium nitrate = Mg(NO₃)₂
So if you remember that a nitrate = NO₃, this task becomes a lot easier.
If you learn the periodic table first and combine this knowledge with the compounds, you’re almost there.
There are enough posts on this forum about learning the periodic table, so let’s skip that and assume you can do that.
How do you remember that nitrate = NO₃? Of course it helps to know (from the periodic table) that N = nitrogen, but your question was how to do this with mnemonics.
First the name. Nitrate sounds like ‘night rate’. Visualize for example a movie being played in a cinema at night, and the movie is cheaper because there is a ‘night rate’.
Now NO₃. Let’s assume you use the Major System for numbers, NO₃ can become mnemonically Not On Monday (m=3).
So the image becomes a movie theater that plays a movie a night. There is a Night Rate, but Not On Mondays.
Great reply Kinma! 
I would have done something along the same line.
Thanks for the compliment, Yan!
excellent dear
Are people using different values for the major system phonetics?
In Kinma’s post the NO3 would not be ‘Not On Monday’ since Monday does not equal 3 as claimed but 31…unless a different phonetic system is being used. By different I mean different than the one used in Harry Lorne’s books.
No. The m from Monday is just to remind you of the 3. Only the m is used. Not the rest of the word.
Kinma nice idea 
please tell
Will tell some more ways so that I can remember my reactions of organic chemistry
