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.

______

  1. Fancium (Fc): A metal found in group 13 and has 4 electron orbitals.

______

  1. 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.
