NAME: An Alien Periodic Table | | I | | | | | | VIII | |---|---|---|---|---|---|---|---| | 1 | Kt | H | | III | IV | V | VI | VII | Oz | | 2 | Ap | R | | T | M | T | Ch | X | Bg | | 3 | Pi | L | | Wa | J | Bj | Za | Hi | Dn | | 4 | Ss | Yz | | G | D | Nu | Q | V | Fx | | 5 | El | Up | | Hf | An | | | | | Procedure Fill in the blank periodic table with the correct alien planet symbol for each element. Symbol is given in parentheses after the element name in the data statements. There is one symbol for each box and each box will be filled. Purpose To correctly place given physical and chemical properties of unknown elements in a blank periodic table. Background Information Earth’s scientists have announced that they have made radio contact with intelligent life on a distant planet. One of this alien planet’s languages has been translated and scientific information has begun to be exchanged. The planet is composed of the same elements as Earth. However, the inhabitants of the planet have different names and symbols for them. Since the alien scientists do not know the names of our elements, they have radioed the following data on the not known properties of the elements. Strangely, but luckily, there are no transition or rare earth elements on the alien planet. This means that their periodic table consists only of the “representative” groups of elements. The data are as follows: The inert gases are Bombal (Bo), Floxxit (Fx), Doadeer (Do), and Oz (Oz). Of these noble gases, Floxxit (Fx) has the largest radius. The valence electrons of Bombal (Bo) are located in its second energy level. Oz (Oz) is a noble gas with 1s² electron configuration. The most common isotope of Doadeer (Do) has a mass number of 40 and contains 22 neutrons. The chemical makeup of the alien planet's oceans seems to be about the same as Earth's oceans. When sea water is distilled, the liquid that is boiled off and then condensed has been shown to have molecules consisting of two atoms of Kratt (Kt), the lightest element on earth, and one atom of Chow (Ch). The solid left behind after the distillation consists mainly of alkali cations of the metal Pi (Pi) and anions of the halogen Highho (Hi). The other alkali metals are Elrado (El), Apatrom (Ap), and Sississ (Ss). Of these alkali metals, Apatrom (Ap) has the least metallic character. Elrado (El) reacts most violently with water. Sississ (Ss) is in the same period as Floxxit (Fx). The other halogens are Vulcania (V) and Xtalt (X). Vulcania (V) is a liquid on earth and the alien planet. The most chemically active non-metal on the planet is Xtalt (X).
