What is Pu? Important knowledge about Pu.

1. Definition of Pu
   Pu, also known as Plutonium, is a chemical element with the symbol Pu and atomic number 94. In English, Plutonium is called “Plutonium”. The atomic mass of Pu is 244 u, and the average atomic mass is 244.664 g/mol. The molecular structure of Plutonium contains 94 protons and 150 neutrons. The ion of Plutonium is typically Pu^4+ with 4 lost electrons.

2. Properties of Pu
   2.1 Physical properties of Pu: Plutonium is a heavy, solid metal with a silver-white color. Under light, it can change to pink or red depending on the viewing angle. Plutonium has no smell and does not have a specific pH level.

2.2 Chemical properties of Pu: Plutonium has the ability to react with oxygen, acids, alkali solutions, and other compounds. Plutonium is a radioactive chemical element, it emits alpha, beta, and gamma radiation.

3. Commonly encountered chemical equations of Pu
   Plutonium is not frequently used in chemical reactions due to its radioactivity.

4. Synthesis of Pu
   4.1 Synthesizing Plutonium in the laboratory is not performed due to its strong radioactivity.
   4.2 In industry, plutonium is produced in nuclear reactors through the neutron absorption process of Uranium-238.
