Yttrium
Yttrium is a silvery transition metal that is commonly used as a component in alloys due to its ability to strengthen and improve the properties of other metals. It also has some unique properties that make it useful in certain applications, such as its ability to absorb atomic radiation and its use as a phosphor in some LED lights. Yttrium can be found in minerals such as gadolinite and xenotime, and is often extracted through a process of ion exchange or solvent extraction. Overall, yttrium plays an important role in many modern technologies and industries.
