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

wise_pancake@lemmy.ca 3 weeks agoDo you guys have to memorize fluorine too?
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.

But… but… muh thulium…
jk all lanthanides are the same don’t @ me physicists
also Ce(IV) catalyst stans also also total synthesis tryhards who think SmI2 is ever the right call

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 iodine in thyroid hormones as an important exception, but chlorine plays a very important role in biology 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.
