Metals Kept in Oil
* Alkali Metals (Group 1): Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), Francium (Fr)
* Alkaline Earth Metals (Group 2): Calcium (Ca), Strontium (Sr), Barium (Ba), Radium (Ra)
Why are these metals kept in oil?
* Extreme Reactivity: These metals react violently with water, oxygen, and even the moisture in the air. They can spontaneously ignite or even explode!
* Preventing Oxidation: Oil acts as a barrier, preventing the metals from reacting with the surrounding environment.
Most Reactive Metal
* Francium (Fr): While Francium is extremely rare, it is the most reactive metal on the periodic table. It reacts explosively with water and air, making it impossible to store in oil.
Important Note:
* Sodium (Na) and Potassium (K) are the most common metals stored in oil. You'll likely find these in chemistry labs.
* Calcium (Ca) is sometimes stored in oil, but it's not as common as alkali metals.
