has anyone ever memorized the periodic table?
My old physics professor has it memorized.jonegil said:has anyone ever memorized the periodic table?

Moonbear said:We had to memorize it when I was in junior high school. :yuck: But, there were a lot less elements on it back then. :uhh:
cyrusabdollahi said:The table is already structured to show trends in orbitals and chemical properties.
It is not necessary since one can readily find it on-line or perhaps print one and put it on the wall. But with time, one can learn the groups, e.g. alkali, alkali earth, halides and noble gases.jonegil said:has anyone ever memorized the periodic table?
Spoken like a true engineer.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.

hey are you going to reply to my pm?
The second from the last column (group 17) is referred to as the ‘Halogens’.jonegil said:i had never seen that group..halides...it certainly corresponds to the "halogéneos" group in portuguese..(F,CL,Br,I and At) i guess.
that's what i thought; if a physicist/chemist used a periodic table on a daily basis it wouldn't take long to memorize it, but the person probably wouldn't think of it as memorization. memorizing it just for fun sounds like a waste of time though.mrjeffy321 said:Useless, I think not. I use the information on the periodic table everyday and it is not even my field of study.
I do think that there is some value in having portions of the periodic table memorized, just as one memorizes the multiplication tables, but I would not go so far as to advocate memorizing the entire table so that you could recreate it from scratch on a blank piece of paper.

shramana said:India. We memorize a lot of useless stuff like log values etc. as well.
ice109 said:you guys don't have calculators that evaluates log?
chaoseverlasting said:We arent allowed to use calculators. Not in high school, not for any tests, not in class, for anything really. I think college is going to be the same to some extent. Vedic/mental mathematics is encouraged (and required actually if you want to pass).
We usually memorize the S/P/D/F block elements with their positions and atomic weights. Radioactive disintegration series. As far as log is concerned, log 2, 3, 5, 7 are memorized, and the "times tables" till twenty.
moose said:ice109, 2, 3, 5, and 7 are chosen because they are the first prime numbers.
chaoseverlasting said:Yeah. You can really simplify calculations and do them a lot faster if you know those log values. It really does make sense.
