why we can’t just take 2 hydrogen atoms and smash them together to make helium.

Idk how I got onto this but I was just googling shit and I was wondering how we are running out of helium. I read that helium is the one non-renuable element on this planet because it comes from the result of radioactive decay. But from my memory and the D- I got in highschool chemistry, helium is number 2 on the periodic table of elements and hydrogen is number 1, so why can’t we just take a fuck ton of hydrogen, do some chemistry shit and turn it into helium? I know it’s not that simple I just don’t understand why it wouldn’t work.

Edit: I get it, it’s nuclear fusion which is physics, not chemistry. My grades were so back in chemistry that I didn’t take physics. Thank you for explaining it to me!

We literally can and do exactly that. That’s what nuclear fusion reactors do, and there’s been some exciting breakthroughs with those lately. Google ITER etc.

>so why can’t we just take a fuck ton of hydrogen, do some chemistry shit and turn it into helium

because like charges repel, so getting the two H nuclei close enough together that they actually fuse requires squeezing the hydrogens together REALLY hard while also heating it to literally *millions* of degrees. [This is a machine we currently use to do it.](https://scx2.b-cdn.net/gfx/news/2022/better-nuclear-fusion-2.jpg)

So the real problem, like so often, is actually money. We DO turn hydrogen into helium, but it takes a billion-dollar fusion reactor to make fractions of a gram of helium this way. All the money in the world couldn’t make a useful amount of helium this way via any method we know of.

TLDR: It’s theoretically possible *and we’ve done it*, but it’s incredibly expensive and makes tiny amounts of helium, so it wouldn’t be worth it.
