Name:__________________________________________ Date:____________________ Honors Chemistry Period________________ Chapter 5: Periodic Trends Earth’s scientists have announced that they have finally made radio contact with intelligent life on a distant planet called JPS-2. One of the alien planet’s languages is being translated, but your assistance is needed. Planet JPS-2 seems to be composed of many of the same elements that are found on Earth. Your task is to use your knowledge of the Earth’s elements to help arrange the alien elements into a blank periodic table. The code letters A to Z have been assigned to 26 elements in the alien planet’s periodic table. 1. In the upper left hand corner, number the blank periodic table below from 1-20 and 31-36 (atomic numbers). 2. Study the given clues and then write Earth’s corresponding element and Alien Element in the space provided. 3. Place the alien symbols in their correct position in the blank periodic table below.
