Unformatted text preview: William Pit t man M ont y St at t on Anna L aur ence Samant ha Jo Cast ellanos 10/11/2007 Construction of an Alien Periodic T able Summary: Various reasoning techniques were used in the constructing of this a lien periodic table. These techniques include many similarities with actual periodic t able formation such as increasing atomic number when moving r ight through rows and when moving down th rough columns with only one exception which will be d iscussed later. The phase (non-metal, metal, semi-metal) and the state (gas, solid, l iquid) also form a parallel between our alien table and the actual table. Our “noble gasses” formed the r ight most column of the alien table, these were adjacent to the non-metals, which were adjacent to the semi-metals, which were adjacent to the metals. The one exception as noted earlier is present because of the boiling points of certain aggiegenide acids. Certain acids must be present in their respective columns, this results in a shift between Ka and Fa (corrected with arrows on my actual table). Metals that exist with variable valences form the bottom two “ removed” rows of the table, these metals can also be referred to as f – block elements because the fill the 4f electron shell. These elements can be referred to as “ removed” because these fifteen elements, according to their atomic number, should be located about in the middle of the table. Although Sw does not exhibit a variable valence, i t does fill its 4f electron shell, therefore it has a place among the bottom t wo rows in the table. Another reason for the table being shaped this way is convenience in portrayal, such as fit ting the table on a regular piece of paper easily. W ith the use of all these techniques and specific properties of these alien elements a feasible table was able to be formed. ...
