Fun educational worksheet titled "The Alien Periodic Table Challenge" where students use their knowledge of Earth's periodic table to arrange alien elements, accompanied by a humorous newspaper clipping about an alien supporting a political candidate.

1. Each alien element symbol should be located in the same position that Earth’s corresponding element symbol would be located.
- Match each alien element to its Earth counterpart based on atomic number, electron configuration, or chemical properties (e.g., valence electrons, reactivity, group trends). For example, if an alien element has 1 valence electron and is highly reactive, it belongs in Group 1 (alkali metals), just like Earth’s lithium, sodium, etc.

2. Label the blank periodic table with each element’s name and symbol. List the evidence you used to justify placement of each element.
- Use known properties: atomic mass, ionization energy, electronegativity, number of electron shells, or common oxidation states. For instance, if an alien element forms a +2 ion and reacts with halogens, place it in Group 2 (alkaline earth metals). If it’s a noble gas with full valence shell, place it in Group 18.

3. Label the names of groups 1, 17, & 18.
- Group 1: Alkali Metals
- Group 17: Halogens
- Group 18: Noble Gases

4. Color-code each of the family groups for the alien periodic table and include a key.
- Assign a unique color to each family (e.g., red for alkali metals, blue for halogens, green for noble gases) and create a legend explaining which color corresponds to which group or family (e.g., “Red = Group 1 – Alkali Metals”).
