Introduction to Periodicity Aliens Introduction to Periodicity

Your Mission NASA has recently found life on a nearby planet! These aliens have many similarities and differences and NASA is in need of a way to organize these life forms. Your job is to create a table to arrange these new life forms.

Getting Started NASA’s instructions: Organize the aliens in a rectangular block. Each group (vertical column) must be the same in some way and must have some feature that changes regularly as you move down the group. Each period (horizontal row) must also share one thing in common and also must have one feature that changes regularly as you go across the periodic table. g r o u p period
