PLEASE help:[ hugeeee test.. How were elements heavier than iron formed?

All of the post-iron elements are formed in supernova explosions themselves. So much energy is released during a supernova explosion that the freed energy and copious free neutrons streaming from the collapsing core drive massive fusion reactions, long past the formation of iron. Sure, this absorbs a lot of energy, but there's plenty available once the explosion has begun.

Hope this helped you!!

Nuclear fusion can create aspects heavier than iron, although this is endothermic. this occurs evidently in a supernova. The heavy aspects in our photograph voltaic gadget weren't created right here.
