| noble gases | elements in group 18 -- do not ordinarily form compounds with other elements |
| semiconductors | substance that under some conditions can carry electricity, like a metal, while under other conditions cannot carry electricity, like a nonmetal |
| plasma | a state in which atoms are stripped of their electrons and the nuclei are packed close together |
| nuclear fusion | when atom nuclei combine to form a larger nucleus, releasing huge amounts of energy in the process |
| supernova | a tremendous explosion that breaks apart a massive star, producing temperatures up to one billion degrees Celsius |
