Alien Element Clues
For each clue from the alien scientists, write what you can figure out about each element.
If you get stuck on a clue, star it and come back to it at the end.
Ex: Livium (Lv): This element is responsible for life.
It has 2 electron energy levels and 4 electrons available for bonding in the outermost energy level.
___Lv is in Period 2
and in Group 14_____________________
1. Explodium (Ex): This element has 5 electron orbitals and is the most reactive metal on the alien's table.
___________________________________________________________________________
2. Fancium (Fc): A metal found in group 13 and has 4 electron orbitals.
___________________________________________________________________________
3. Nebulaum (Nu): This is the lightest of elements; aliens previously used it in their aircraft until their
aircraft caught fire in a horrific accident. It is a very reactive gas.
___________________________________________________________________________
4. Moonium (Mm): An element with 45 neutrons and 34 protons.
___________________________________________________________________________
5. Balloonium (Bn): A noble gas that is nonreactive. It is less dense than the air in our atmosphere.
___________________________________________________________________________
6. Metalloidium (M) and Poisonium (Ps): Two metalloids found in period 4. Ps is more massive than M.
___________________________________________________________________________
7. Lowigium (Lo): A group 17 halogen with 4 electron orbitals.
___________________________________________________________________________
8. Darkbluium(Dk): Has 66 neutrons and 49 protons.
