How do you memorize polyatomic ions in chemistry?
Which polyatomic ions should I memorize?
The suffixes of the names of polyatomic ions have a pattern associated with them. If you will notice, oxyanions end with the prefixs “ate” and “ite.” The key to memorizing the names of oxyanions is knowing the difference between the “ate” and “ite” suffixes.
How hard is it to get a 5 on AP Chemistry?
Usually, only the most driven students take AP Chemistry, and they’re still not passing the test at an especially high rate. We can also look at the 5 rate for the test. The 5 rate for AP Chemistry is 11.5%. Only nine other AP tests have lower 5 rates.
What should I memorize for chemistry?
For example, a mnemonic to memorize the first elements of the periodic table is “Hi, he lies because boys can not operate fireplaces.” This translates into hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine. You could choose other words to stand for the letters.
How do you memorize polyatomic charges?
Use a mnemonic device to help remember the charges. For example, Mr. P of Papa Podcasts developed the phrase “Nick the Camel ate a Clam for Supper in Phoenix” to remember the polyatomic ions that end in “-ate.” The “-ate” is indicated in the sentence itself for easy memory.
How do you memorize polyatomic ions on the MCAt?

Is AP chem or bio harder?
However, our son thinks taking AP bio in junior year makes more sense since AP biology tends to be relatively ‘easier’ than AP chemistry for most kids and his next year classes are rigorous.
Is AP Chem harder than college chem?
AP Chem is a great class to determine where you stand in the science field. It is by far the most difficult class on campus, but the most rewarding as well. A couple of guidelines for your success, number 1 don’t take AP Physics along with Chemistry, they are two tough courses that can drive you crazy.
Does chemistry require memorization?
yes it is mostly memorization at A level. If you carry on with physics at uni you’ll find that you learn how to explain/understand quite a few things that just have to be limited to memorization in A-level chemistry.
How can I study chemistry in one day?
Is the MCAT mostly memorization?
The MCAT is not a memorization test. Let me be more specific: it’s much more about recall than it is about recognition. When you’re prepping for the Psych/Soc section of the MCAT, you’ll learn about different types of memory—sensory, working, procedural, episodic—how memory is stored, and how it’s retrieved.
