What is Sb2? Important Knowledge about Sb2

Firstly, you need to know that Sb₂ is not a specific chemical substance but rather a symbol of the Antimony atom (Sb) in molecular state. In this lecture, we will learn about Antimony.

1. Definition:

1.1 Names:
1.1.1 Common name: Antimony
1.1.2 English name: Antimony

1.2 Atomic mass: 121.760 u.

1.3 Atomic weight: The atomic weight of Antimony (Sb) is 121.760.

1.4 Ion structure: Antimony forms ions Sb₃+ or Sb₅+ in chemical reactions.

2. Properties:
   2.1 Physical properties: Antimony is a chemical element with a silver-gray color, odorless and insoluble in water.

   2.2 Chemical properties: Antimony mainly reacts with strong oxidants such as halogens, oxygen, and strong acids.

3. Common chemical equations:
   Since Sb₂ is not a specific chemical substance, it is not possible to provide chemical equations related to Sb₂.

4. Preparation:
   4.1 Laboratory preparation: Antimony is usually not prepared in the laboratory because this process requires high conditions and is hard to control.

   4.2 Industrial preparation: In the industry, antimony is produced from stibnite ore (Sb₂S₃) through thermal and chemical processes.
