 The Star Trek Spaceship Voyager accidentally encounters a Gamma Quadrant that traps them in a universe with quite different physical laws from those with which we are familiar. Investigating the chemical elements in the alternative universe, the astronauts discover these properties:

1. Arrange these elements into a periodic table. [NOTE: All elements in the first row have been identified. All periods, if complete, would contain the same number of elements.]
2. If a new element, E, with atomic weight 23.1, were discovered, what would its properties be?
3. Are there any other elements that have not yet been discovered? If so, what would their properties be?
