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 (e.g.
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
12
example using our own symbols – you will use the alien symbols.
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.  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. 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. Bu has 1 electron in its outer energy

level, Bw has 2, Xi has 3, Cc has 4, Bl has 5, Sk has 6, P has 7 and Sb has 8.  our sodium, magnesium,
aluminum, silicon, phosphorus, sulfur, chlorine, and argon (going across 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
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
Abundantcium(Ab): One of the most abundant gasses in the universe, it has a total of 7 electrons when
neutral.  our nitrogen
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;  our
tellurium (only group 6A element left) Boracium (B): 3  our boron (only group 3A element left)
