The remaining elements of the periodic table were produced via successive nuclear fusion in stars (up to iron), and under the intense pressures and temperatures of supernova explosions (up to uranium).]]> 2018-02-27 16:54:36 UTC https://padlet.com/cacraig/4xo9xqdfakal/wish/235997743 https://padlet.com/cacraig/4xo9xqdfakal/wish/240863568 Luster, Scratch, and Hardness.]]> 2018-03-12 13:54:18 UTC https://padlet.com/cacraig/4xo9xqdfakal/wish/240863568
