1 alien periodic Chart Materials: periodic table Notes on the periodic table Pencil But most importantly, your brain! Procedure: You are a part of a collection of scientists who have been chosen to assist a group of alien scientists. In order to be able to converse scientifically, you must learn their language, and most importantly, you must arrange their elements according to the trends that exist in the periodic table . Below are clues for the alien 's elements. So far, the aliens have only discovered elements in groups 1, 2, and 13-18, and periods 1-5. Although the names of the elements are different, they must correspond to our elements if our belief of universal elements holds true ( a neutral atom with 6 protons anywhere in the universe will be the same atom as what we know as carbon). Read each clue carefully, and then place the alien symbol, atomic number, and most likely isotope symbol for that clue's element in the blank periodic table provided (see the box at the right for an example using our own symbols you will use the alien symbols.)

2 1. Livium (Lv): This element is responsible for life. The aliens call living things the equivalent of livium-based organisms. It has 2 electron energy levels and 4 electrons available for bonding in the outermost energy level. our carbon 2. Computerchipium (Cc): This element is important for its use as a semiconductor in computers (it has 4 valence electrons, and 3 energy levels) our silicon 3. Lightium (L): This is the lightest of elements, it s the only element on the table that usually has no neutrons. our hydrogen 4. Breathium(Br): When combined with Lightium (L), it makes the alien 's most common liquid whose formula is L2Br, this liquid is what makes up most of the alien s body. our oxygen (H2O L2Br) 5. Francium (F): A metal found in period 4 group 13. our gallium 6. Moonium (Mo): An element with an atomic number of 34. our selenium 7. Explodium (Ex): This element is the most reactive metal on the alien 's table .

3 Our Rubidium (since their table only goes to period 5) 8. Violetium(V): This element is found as part of a compound in bananas. It is member of the alkali metal family, and is the second most reactive metal on the alien s periodic table . our potassium 9. Sparkium (Sp) and Burnium (Bu) are members of the alkali metal group, along with Violetium(V) and Explodium (Ex). Their reactivity, from least to greatest, is Sp Bu V Ex. our Lithium, Sodium, Potassium, and Rubidium 10. Balloonium (Ba): A noble gas used to fill balloons to help them float. our helium 11. Toothium (To): This element in group 2 is found in milk, and is added to juices to help build strong bones and teeth. our calcium 12. Metalloidium (M) and Poisonium (Po): Two metalloids found in period 4. Po is the more massive than M. our germanium and arsenic 13. Lowigium (Lo): A period 4 halogen. our bromine 14.

4 Darkbluium(Dk): Has a mass number of 115 for the most common isotope. our indium 15. Hugium (Hu): The element on the alien 's periodic table that has the most mass. our xenon (because their table only goes up to period 5) 16. Glucinium (Gl): The element found in period 2, group 2. our beryllium 17. Reactinium (Re): The most reactive nonmetal on the periodic table . our fluorine 18. Balloonium (Ba), Signium(Si), Stableium(Sb), Supermanium (Sm), and Hugium (Hu) are all noble gases. They are arranged above from least to most massive. our helium, neon, argon, krypton, and xenon 19. Cannium (Cn): This element is often used as a container in which to preserve foods, this element has 5 energy levels occupied in its ground state. our tin 20. Burnium (Bu), Blue-whitium (Bw), Bauxitium (Xi), Computerchipsium (Cc), Bringer-of-lightium (Bl), Stinkium (Sk), Purium (P), and Stableium (Sb) are all found in period 3.

Scottishium (Sc): A metal element found in group 2. our strontium (the only group 2 metal left on their periodic table not found elsewhere 22. Infectium (If): This element, mixed with alcohol, is used on cuts (turns the skin yellow where applied), and is least reactive member of the halogen group on the alien s periodic table . our iodine 23. Abundantcium(Ab): One of the most abundant gasses in the universe, it has a total of 7 electrons when neutral. our nitrogen 24. Some additional clues: The number after the symbol indicates the number of electrons in the outer energy level: Notalonium(Na): 5; our antinomy (only group 5A element left) Earthium (E): 6.)

6 Our tellurium (only group 6A element left) Boracium (B): 3 our boron (only group 3A element left) alien periodic Chart Period: Name: Physical Science Date: Write the atomic number, the alien s element symbol, and the symbol of the most likely isotope from the alien s periodic table into the correct spots on our periodic table Transition Metals IIIA 13 IVA 14 VA 15 VI 16 VII 17 VIII 18 IA 1 IIA 2 1 2 3 4 5 Atomic # alien symbol mass # alien sym Template 1 L 1L 2 Ba 4Ba 3 Sp 7Sp 4 Gl 9Gl 5 B 11B 6 Lv 12Lv 7 Ab 14Ab 8 Br 16Br 9 Re 19Re 10 Si 20Si 11 Bu 23Bu 12 Bw 24Bw 13 Xi 27Xi 14 Cc 28Cc 15 Bl 31Bl 16 Sk 32Sk 17 P 35P 18 Sb 40Sb 19 V 39V 20 To 40To 31 F 70F 32 M 73M 33 Po 75Po 34 Mo 79Mo 35 Lo 80Lo 36 Sm 84Sm 37 Ex 85Ex 38 Sc 88Sc 49 Dk 115Dk 50 Cn 119Cn 51 Na 122Na 52 E 128E 53 If 127If 54 Hu 131Hu
