I’m a biochemist and I think the periodic table is easy to memorize. “Hydrogen, blah blah blah, carbon, nitrogen, oxygen” and that’s it. Wait, hold on, sodium and chlorine are also on there somewhere…
My undergrad biochemistry course was taught team taught by a microbiologist and a molecular biologist because the biochemist got fired for sexually harassing a few students.
The molecular biologist was a cool guy and taught concepts. I got an easy A in that section.
The next few weeks were taught by the microbiologist. That asshole wanted us to memorize a ton of different pathways on our second midterm (cyclic acid, fermentations, photosynthetic, MAPK etc…). Something like 20 total. I took an F on that one.
Luckily the final was a standardize test that all universities in the state used that year. So I ended up with a B.
It’s been a decade since I took chemistry, and I did not get very good marks in it, but it seems like the elements at the bottom of the table (with exception to Uranium and Plutonium) are just hanging out while the top elements do all the work.
Fluorine is extremely rare in biological systems. (I was going to say “never” but I looked it up and apparently there are a couple of exotic compounds that have it.) However, fluorine is a component of many man-made drugs and poisons. Halogens are generally not incorporated directly into bio-molecules (with exceptions, the chief one being iodine in thyroid hormones) but chlorine plays an essential role in all living things as a free, negatively charged ion.
Some heavier, metallic elements in the form of ions are necessary for the function of many enzymes, but biological systems can’t work with chemically bound metals the way that human technology can. I looked up what the heaviest element with a biological role is and the answer is apparently tungsten (although I’ve never come across an enzyme incorporating tungsten during the course of my work) but even heavier metals can act as poisons by taking the place of lighter, catalytically active metals in enzymes.
It can be fun to look at the Wikipedia article of some weird element that never seems to be mentioned and see what strange uses humans have actually found for it.

Phosphorus, sulfur, …?
I don’t like to talk about cysteine.

Do you guys have to memorize fluorine too?

If it’s too big to be created in self sustaining fusion it’s too big to give a shit about.
