    Everything except hydrogen. And technically, only elements that are heavier than iron necessarily come from exploding stars. The lighter elements are made in non-exploding stars and could, at least theoretically, be distributed across the universe without a supernova.

      Lithium as well, if I recall correctly. Most lithium is theorized to date to the big bang. There are no current pathways to create it, and only pathways that destroy it.

      Most helium also dates to big bang, but some was created through fusion or alpha decay.
