1.1 Lu, or Lutetium, is the English name of the chemical element with the symbol Lu and atomic number 71. It is a transition metal belonging to the Lanthanide group in the periodic table. The atomic mass of Lutetium is 174.97 atomic mass units (u). Its molecular structure is very complex, and it does not form any ions under standard conditions.
2.1 Lu is a silver-white metal, odorless and does not have the ability to change the pH of a solution. It has good electrical conductivity.
2.2 The chemical properties of Lu are minimally affected by chemical influences. It does not participate in oxidation/reduction reactions and is quite stable against chemical influences.
-
Because Lutetium does not participate in many chemical reactions, there are not many examples of chemical reactions with metals, acids, nonmetals, or salts involving Lutetium.
-
The synthesis of Lu is very complex and requires extensive knowledge of chemistry. Therefore, the synthesis of Lu is not performed in school laboratories. On an industrial scale, Lu is produced from xenotime or monazite ore through several steps of purification and separation.
Note: Lutetium is a rare chemical element and is not widely used in everyday life. Therefore, it is not specifically taught in high school chemistry curriculum. However, mastering knowledge about it will help students broaden their understanding of chemistry and chemical elements.
