Introduction Our problem begins with presentation of an alien world with an assorted accumulation of alien elements. Each alien element is similar to atoms in the present “normal” periodic table but have not order in which to be organized. The purpose of the experiment is to develop a plausible, creative, and imaginative periodic table involving a system of order to organize the alien atoms. For the most part, the way we set up the table was primarily determined by reactivity. By using this as an initial determinant, we were able to isolate the basic structure of the table into periods and groups. This not only organized the body, but also organized the elements into groups with similar chemical reactions and properties. With the almost completion of the image of a periodic table we desired, we came to the conclusion that reactivity is an important if not the key factor in developing both the alien and “normal” periodic tables. Electron negativity and affinity ran in accordance with the reactivity. These became second determinants as well as supporting factors in the general

shaping of the table. Finally, since there was an extended periods, we relocated the periods below the main section. These periods were based off the reactivity considering that some were unreactive. However, although the relocation of the periods is similar with relations with the lanthanides and actinides of the “normal” table, ours are offset from each other.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
