+ Chemical element, Compounds: Nuclear physics
  * In many cases, these compounds have a fixed composition and their own structure and properties. The properties of the compound may be very different from the elements it is made from. Sodium is a metal that burns when put into water and chlorine is a poisonous gas.
+ Phosphide: Phosphorus compounds
  * Phosphide' is an ion. It does not always have that formula. It is a reducing agent. Sodium phosphide is an example. Some phosphides are semiconductors and are not ionic with P3- ions. They are less reactive. Some metals form alloys with phosphorus to make phosphides. If it is ionic, then the phosphorus is in the -3 oxidation state.
+ Sodium phosphide, Properties: Phosphorus compounds :: Sodium compounds
  * Sodium phosphide is a black solid. It is ionic. It reacts with acids to make phosphine gas. It is a reducing agent
  - Safety
  * Sodium phosphide is flammable, making toxic gases when burned. It also makes toxic flammable gases when reacted with acids
+ Sodium, Properties: Alkali metals :: Chemical elements
  * Sodium is a light, silver-coloured metal. Sodium is so soft that it can be easily cut with a knife. When it is cut, the surface will become white after a bit of time. This is because it reacts with air to form sodium hydroxide and sodium carbonate. This reaction is very fast. Hydrogen and sodium hydroxide are produced.
