Question 2: During the late 19th and early 20th century, Marie Curie and her husband
discovered polonium and radium. Once they started exploring the properties of these
metals, they coined the term "radioactivity".
Through their discoveries, scientists gained more information about atoms and
elements.
Think about what you know about the physical and chemical properties of elements
In CER(claim, evidence, reasoning) format:
1. Tell a story of how you discovered a newl fictitious element.
2. Describe any unique physical and chemical properties of the element
3. Give it a name.
4. Explain where this element would be located on the periodic table.
