I think it that when a supernova occurs it can be as hot as 1 billion degrees C. I also think that when a supernova occurs that it can create and blow off the very heavy elements.

I like learning what is reactive to each other because I like mixing things together and seeing what happens. I also liked how plasma is made by atoms that were stripped of their electrons. Finally I think it was amazing that Mendeleev just woke up one day and wrote down what was in his head about the perotic table.

Ah, time zone setting must be off (set to default UTC time… which is really interesting: http://en.wikipedia.org/wiki/Coordinated_Universal_Time ).

All fixed now!

I found it interesting how nuclear fusion occurred to create new elements. When two atomic nuclei combine it forms an element on the periodic table. Also when helium builds up in a sun’s core other fusion reactions happen and it makes new elements. In this video it shows how a new star gets most of its energy from H and He. H and He are the main start of new elements inside of the star as fusion occurs. As fusion continues, many new elements are created. Once a star creates iron, this is the endpoint of the star. A supernova occurs and blows up the star. The supernova then creates the rest of the elements on the periodic table.
