Where are the heaviest nuclei of all formed?

Answer 1

Elements heavier than iron are formed through the fusion reaction in stars when a supernova occurs. The lighter elements up through iron are formed in "regular" stellar fusion, and this is what powers most stars throughout their lives. A lot of energy is created in the fusion reactions, and this is why stars "burn" the way they do. But after iron, fusion switches from exothermic to endothermic. That means energy must be put into the fusion reaction to create these heavier elements, and only when a super abundance of energy is available, like during the collapse of a star in a supernova, is there sufficient energy to drive those fusion reactions. All the trans-iron elements up through uranium are created in the supernova.

Answer 2

In stars. The fact that we have heavier elements here on Earth (and therefore life!) is due to the fact that at some moment, a massive star (or several) produced those heavy elements, and part of this material went out into outer space in a supernova explosion (or several).

Answer 3

High mass elements are formed during the death of a star. Examples of star death are both novas or supernovas.

Answer 4

they were formed by God, the creator of the universe and everything in it and outside it.

Answer 5

The heaviest known nuclei are created artificially, in labs on Earth. The heaviest natural nuclei are created in stars - for example in supernovae - and then expelled into space.

Answer 6

In the inside of stars. They were released from there in supernova explosions.

Answer 7

Chemical elements are created by stellar nucleosynthesis.

Answer 8

In supernova explosions.
