I accidentally memorized it in high school. Well, most of it. I don't remember it anymore though.
EDIT: about periodic table from op.

If you want to have to do anything related to chemistry, it's extremely helpful to have a good picture of the PT stored in memory. Every time you come across some relationship between properties of two compounds, the likelihood of it setting off a lightbulb in your head is directly proportional to whether or not you've got the PT memorized. If you haven't memorized the PT, you will miss out on figuring out so many of the reasons why things are the way they are. And without the help of this explanatory logic, you have to take up additional memory space just to remember these facts without basis.cyrusabdollahi said:What would be the point in memorizing such useless information? Thats the whole reason why its ordered in a table for you to look up.

I memorize the PT because that way, I have to remember fewer things in chemistry.

Memorizing atomic numbers and symbols is useful, believe me, as is memorizing a few of the atomic weights of elements.cyrusabdollahi said:How does memorizing atomic weights, or atomic number, or atomic symbol help? How does that explain why things are the way they are? I would think spdf orbitals are the only things of real value, and those are already in order by the way the table is ordered. So you can look at the table and find the orbital instantly since you know how its arranged.

If one is doing calculations and has constantly refer back to the periodic table for every single bit of information then one is slowed down considerably.
It is much quicker to have the atomic number of Oxygen memorized (8) and know that its molar mass is 16.00 g/mol. There are several elements which are so common that you will naturally memorize their information; you don’t need to do this for all elements however...for example the molar mass of Bohrium (264 g/mol) doesn’t come up that often in my experience.
cyrusabdollahi said:I HATE having to memorize ANYTHING. If its important to remember, you will remember it from using it from experience. (Which is exactly what you are describing). What the OP is describing, is memorizing the PT to take an exam, and that is worthless information (even though its the same information, because it has no purpose other than to take an exam).
That's why there is the saying "Either you use it or you lose it."
