iron
A massive star with iron in its core will stop nuclear fusion, leading to its collapse and eventual explosion as a supernova. Iron is the element at which fusion becomes endothermic, meaning energy is no longer released in the process.
The sun and other stars.
The products of nuclear fusion are slightly less massive than the mass of the reactants because some of the mass of the reactants is converted into nuclear binding energy to hold the fusion product together.
Yes, radium is a radioactive element that can emit radiation and is used in some types of nuclear reactions to produce energy. It is not commonly used in nuclear power plants but has been used historically in early experiments to explore nuclear reactions.
Yes, uranium is a stored form of energy. It is a radioactive element that can undergo nuclear fission, releasing a significant amount of energy in the form of heat. This heat can be harnessed to generate electricity in nuclear power plants.

The energy in stars comes from nuclear fusion. Hydrogen atoms are continually fused together to created helium and with it, massive amounts of energy.
The human element.
Uranium
The final core element for a massive star is iron. When a massive star exhausts its nuclear fuel, iron builds up in its core due to fusion reactions. Iron cannot undergo further fusion to release energy, leading to a collapse and subsequent supernova explosion.
No, iron is not the heaviest element made in massive stars. Massive stars produce elements through nuclear fusion in their cores, creating heavier elements than iron, such as lead, gold, and uranium. Iron is often referred to as the endpoint of nuclear fusion in massive stars because the energy required to fuse iron exceeds the energy output of the reaction.
One type of atom (element or isotope) is converted to another. This is called nuclear reaction.
Uranium 235
Uranium.
Uranium is the most commonly used radioactive element for nuclear energy production. When uranium atoms undergo nuclear fission, they release energy that can be harnessed in nuclear reactors to generate electricity.
An explosive device that uses massive conventional explosives to split radioactive atoms and cause a MASSIVE release of energy by nuclear fission or fusion. A BIG BOOM!!!!
Uranium is the primary element used in nuclear power plants for its ability to undergo nuclear fission and produce energy.
