29 In an alien world, a different periodic table exists. It is organized similar to the periodic table in our world, just smaller. The first group contains the alkali metals, the second group the alkaline earth metals, there are a few transition metals, and then some non-metals. The periodic table is shown below in picture form, and a table is given with molar masses and common ionic charges. Also in the table is a list of common ion groups (similar to carbonate, nitrate, etc. in our world.) Below is a table showing the molar masses and common ionic charges Element Symbol Atomic Number Atomic Mass Common Charge(s) FixedOrVariable Element or Group Name of anion Hydrogen H 0           Jellium J 1 1.28 2 Fixed Element   Dogium D 2 2.48 -3 Fixed Element Dogide Gorillium G 3 4.87 -2 Fixed Element Gorillide Monkium M 4 7.27 -1 Fixed Element Monkide Jucium Oj 5 9.39 1 Fixed Element   Racium R 6 11.18 2 Fixed Element   Romium Ro 7 14.05 -3 Fixed Element Romide Julietium…
