Splitting Helium doesn't release energy.

SPREADING MISSINFORMATION ONLINE!

Who's this "Miss Information"?

[–] Klear@lemmy.world 24 points 2 years ago (1 children)

I don't know, but I heard she's spreading.

[–] spauldo@lemmy.ml 12 points 2 years ago

She really gets around, if you know what I mean.

minor spelling mistake 😔

I think the joke would work with Radon though.

[–] spauldo@lemmy.ml 7 points 2 years ago (2 children)

IIRC, Radon hasn't been proven to be a noble gas. Xenon is downright promiscuous compared to the other noble gases, and some chemists think that trend continues into radon.

And when you trap a xenon inside a C60 cage and start stuffing other things in there, the chemistry gets really weird.

I mean, it's in the column. Close enough.

People across the board think that they will never need any math or science after leaving school. That's how you get jokes that anyone who was not asleep in physics would not have created.

Splitting a random atom wouldn't cause a chain reaction anyway. It's just a meme, lol.

[–] Wogi@lemmy.world 1 points 2 years ago (2 children)

....I need to know more. We can just break open helium all Willy nilly? What's the biggest atom we can safely split?

[–] paholg@lemm.ee 9 points 2 years ago (2 children)

Atoms lighter than iron take energy to split, and release energy when fusing. For atoms heavier than iron, it's the opposite.

You lose energy if you split or fuse it

[–] AngryCommieKender@lemmy.world 3 points 2 years ago* (last edited 2 years ago)

It extinguishes the stars it forms in. Once you have enough Iron, and the amount is actually quite small compared to the rest of the mass of the star, that triggers a nova. This is due to Iron needing extra energy to either fuse or fission.

[–] TechieDamien@lemmy.ml 3 points 2 years ago

Close, the maximum binding energy per atomic mass unit is iron-56, but splitting heavier atoms does not guarrentee releasing energy. If you consider the graph of specific bonding energy against atomic mass, then also consider that you need two numbers that add up to the original mass, it is clear that you need approximately more than 100u to release energy on fission.
