I have a degree in chemistry and I never had to do this. ~98% of the time you’re working with the same 5 elements. Many elements on the table literally only existed for a microsecond in a lab decades ago.
Same on everything except my professors actually made us memorize ~15 because we used them so frequently in gen chem and they said it would help on timed tests.
Now I just keep a periodic table as my computer desktop and posted in the lab.
