For clue 5 on your mission, you are asked to visit the LARGEST of the Alkali Metals. Identify the name of this element and give its the group number, period number, symbol and atomic mass for the most rare element in this family. Tell me what its "magical power" is that makes it very rare. (6 points total) with 223 u

Answer 1

The largest alkali metal is francium. Here’s the information you requested:

• Element Name: Francium
• Group Number: 1
• Period Number: 7
• Symbol: Fr
• Atomic Mass: Approximately 223 u

Magical Power: Francium is extremely rare because it is highly radioactive and has a very short half-life. The most stable isotope of francium, ^223Fr, has a half-life of only about 22 minutes, making it difficult to find in nature and leading to its classification as one of the rarest elements.
