Is phosphorus a gas?
Is phosphorus a gas?
phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.
Is phosphorus a gas or metal?
Phosphorus is a non-metal that sits just below nitrogen in group 15 of the periodic table. This element exists in several forms, of which white and red are the best known.
Is red phosphorus a gas?
Poisonous gas Red phosphorus can react with hydrogen to produce phosphine – but not with hot water. White phosphorus can react with sodium hydroxide (a chemical he would have had) but you can see he throws in a red powder, rather than a white substance.
What category is phosphate?
Phosphate group: A functional group characterized by a phosphorus atom bonded to four oxygen atoms (three single bonds and one double bond). One of these oxygen atoms must be bonded to another atom; if not, the structure is a phosphate ion.
Is phosphate a solid liquid or gas?

Is Potassium a gas?
Classified as an alkali metal, Potassium is a solid at room temperature.
Is phosphorus a solid?
Phosphorus is a chemical element with symbol P and atomic number 15. Classified as a nonmetal, Phosphorus is a solid at room temperature.
How do you make phosphorus gas?
phosphine (PH3), also called hydrogen phosphide, a colourless, flammable, extremely toxic gas with a disagreeable garliclike odour. Phosphine is formed by the action of a strong base or hot water on white phosphorus or by the reaction of water with calcium phosphide (Ca3P2).
How do you make phosphate gas?
Preparation and occurrence Industrially it can be made by the reaction of white phosphorus with sodium or potassium hydroxide, producing potassium or sodium hypophosphite as a by-product. Alternatively, the acid-catalyzed disproportionation of white phosphorus yields phosphoric acid and phosphine.
Is phosphate an element?
Phosphates are the naturally occurring form of the element phosphorus, found in many phosphate minerals. In mineralogy and geology, phosphate refers to a rock or ore containing phosphate ions.
Is phosphate a mineral?
phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid, H3(PO4). More than 200 species of phosphate minerals are recognized, and structurally they all have isolated (PO4) tetrahedral units.
Is phosphorus a mineral?
Phosphorus is the second most abundant mineral in the body, second to calcium. About 85% of the body’s phosphorus is stored in bones and teeth.
