Where Elements Come From — "Iron is the Boundary"
Below iron (H to Fe): made by stellar fusion (normal star lifetimes)
Above iron (Cu, Au, Pb, U...): made by supernovae only
Iron (Fe) is the most stable nucleus — fusion cannot release energy from iron or heavier elements.
Quick Check: Why do massive stars have shorter lives than less massive stars, even though they have more fuel?
Massive stars have greater gravitational compression, which means their cores reach higher temperatures and pressures. This makes nuclear fusion happen at a much faster rate. Even though they have more hydrogen fuel to start with, they burn through it so much faster that their total lifetime is much shorter — millions of years rather than billions.
