Chemical Formula of Sodium Sulfide
On the chemical formula of sodium sulfide
In the process of chemistry, the chemical formula of sodium sulfide is a key question. Sodium sulfide is composed of sodium ($Na $) and sulfur ($S $).
Sodium, an active metal element, is only one electron in the outermost layer of its atom, which is volatile and shows a $+ 1 $valence. Sulfur, a non-metallic element, has six electrons in the outermost layer of its atom, and wants to obtain two electrons to achieve an octet stable structure, so it often shows a $- 2 $valence.
According to the principle that the sum of the valence algebra of each element in the compound is zero, in order to make the sum of the valence algebra of sodium and sulfur in sodium sulfide zero, a disodium atom needs to be combined with a sulfur atom. Therefore, the chemical formula of sodium sulfide is $Na_ {2} S $.
The chemical substances in view are each formed into a specific chemical formula according to their elemental characteristics and synthesis rules. This rule is also the cornerstone of chemistry. It helps us to clarify the composition of matter and explore the mysteries of chemistry. It is of great significance to the study and practice of chemistry.
