Hello Planet Earth-Planet Orkadoo Calling!!
You earthlings have been contacted by an alien planet to help them with their periodic table. You have been hired to use the data from Planet Orkadoo’s scientists to recreate their Periodic Table.
Background Information of the planet Orkadoo!!
Planet Orkadoo is in the Gliese 581 system. The intelligent life on Planet Orkadoo has made contact with scientists on Earth. Planet Orkadoo’s languages have been translated, and scientific information has begun to be exchanged.
The planet is composed of the same elements as Earth, except that there are no transition or synthetic elements on Planet Orkadoo. This means that their Periodic Table consists of 30 elements that belong to Groups 1, 2, 13, 14, 15, 16, 17 and 18. However, the
inhabitants of the planet have different names and symbols for them. Since the scientists on Planet Orkadoo do not know the names of our elements, they have radioed data about the properties of their elements.
The data from Planet Orkadoo follows:
1. The noble gases are bombal (Bo), wobble (Wo), jeptum (J), and logon (L). Bombal (Bo) is a noble gas but does not have 8 valence electrons. The outside energy level of logon (L) is its second energy level. Of these noble gases, wobble (Wo) has the
greatest atomic mass.
2. The alkali metals are xtalt (X), byyou (By), chow (Ch), and quackzil (Q). Of these alkali metals, chow (Ch) has the smallest atomic mass. Quackzil (Q) is in the same period as wobble (Wo).
3. The halogens are apstrom (A), vulcania (V), and kratt (Kt). Vulcania (V) is in the same period as quackzil (Q) and wobble (Wo).
4. The metalloids are ernst (E), highho (Hi), terriblum (T), and sississ (Ss). Sississ (Ss) is the metalloid with the highest atomic mass. Ernst (E) is the metalloid with the lowest atomic mass. Highho (Hi) and terriblum (T) are in Group 14. Terriblum
(T) has more protons than Hi. The element called yazzer (Yz) is a metalloid by location but has properties that suggest it is a light metal.
5. The most metallic element on the planet is called xtalt (X). The most chemically active nonmetal on the planet is called apstrom (A). The lightest element on the planet is called pfsst (Pf). The heaviest element on the planet is elrado (El). It is
highly radioactive.
6. The chemical makeup of the alien planet's oceans seems to be about the same as Earth's oceans. When seawater is distilled, the liquid that is boiled off and then condensed has been shown to have molecules consisting of two atoms of pfsst (Pf) and
one atom of nuutye (Nu). The solid left behind after the distillation consists mainly of a crystal made up of the elements byyou (By) and kratt (Kt).
7. The element called doggone (D) has only 4 protons in its atom.
8. Floxxit (Fx) is a black crystal and has 4 electrons in its outermost energy level. Both rhaatrap (R) and doadeer (Do) have atoms with four energy levels. But rhaatrap is less metallic than doadeer.
9. Magnificon (M), goldy (G), and sississ (Ss) are all members of Group 15. Goldy has fewer total electrons than magnificon.
10. Urrp (Up), oz (Oz), and nuutye (Nu) all belong to Group 16. Nuutye is diatomic. Oz has a lower atomic number than urrp.
11. The element anatom (An) belongs to Group 13. The elements zapper (Z) and pie (Pi) both belong to Group 2. Pie (Pi) has five energy levels, while zapper has three.
Now that you have the data (Element Name/symbols and information) from the scientists from Orkadoo, you will place their elements in the periodic table according to the colour coding given below and explain why you have positioned them in that particular
place in the periodic table.
