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) like the biggest

Answer 1

The largest of the alkali metals is cesium (Cs). Here are the details you requested:

• Element Name: Cesium
• Group Number: 1
• Period Number: 6
• Symbol: Cs
• Atomic Mass: Approximately 132.91 amu

Magical Power

Cesium is considered very rare in terms of its stable isotopes due to its unique property of being the most electropositive and alkaline element in the periodic table. Cesium's "magical power" lies in its use in atomic clocks, where it defines the second based on the frequency of microwave radiation emitted by cesium atoms. This property makes it essential in precise timekeeping, GPS systems, and various scientific applications, highlighting its rarity and significance in both technology and fundamental physics.
