Finallly, took me so long to find it. Thanks dude! Everyone just keeps saying its bcos fusion eventually becomes endetermic but im always like why? youre the first one to explain .

[ninefox]

Excellent and concise explanation, thank you!

Legend, Got my A-level physics in 3 days and finally understand this, thanks!

[onatsakall]

THANK YOU!!!! I've been going crazy over this

[yeaaano]

i love that. not recycling the same five topics on how fission/fusion works, learned something new, thanks!

[yo-pqee]

bruh thanks so much, great explanation

Quick clarification: a reaction only releases energy if the average Binding Energy or BE per Nucleon is increased. This is the total BE divided by the number of protons and neutrons in the nucleus and represents the amount of energy required to remove one particle from the nucleus.

So a reaction can increase the binding energy but not release energy because the average BE is less. Conversely, a reaction that decreases overall binding energy can still release energy if the number of nucleons decreases enough that the average BE still increases.

Hope this helps!

But if binding energy is increased, why is more energy released?

How is an uranium atom is more stable than hydrogen and helium 🤯🤯🤯🤯
