Interestingly, white phosphorus, the most common allotrope of phosphorus, is defined as the standard state despite the fact that it is only metastable. For all the other solid elements, the "standard state" is defined as the most stable allotrope at 100 kPa. Red, violet, and black phosphorous are more stable, but far less common since they require special conditions to be produced and even being more stable are still very reactive. Note that red phosphorous might actually be considered just an intermediate phase between white and violet phosphorous rather than an allotrope, and consequently most of its properties vary considerably.
In chemistry, an allotropism is the ability of an element to exist in more than one physical form without a change of state.
phosphorus
Phosphorus is not important as a conductor.
Phosphorus (P) has 15 protons and 15 electrons. Phosphorus-31, the only stable isotope of Phosphorus, has 16 neutrons.
its a solid it will ignite! be careful with it
solid state
At normal temperatures, phosphorus is a solid.
gas
Phosphorus can, in fact, exist as covalent crystals in the solid state. Phosphorus usually exists in the solid state as non-covalent crystals. Under intense pressure, however, the bonds can become covalent.
Phosphorus stays in tetra atom form in its elemental state and its formula is P4
The oxidation no of phosphorus is +3 and that of chlorine is -1.
phosphorus, the second member,though a solid, can pass readily into vapour state.
Element Phosphorus has an oxidation state of -4. No element has oxidation state of +4. Phosphorus is denoted by "P".
Phosphorous Is A Solid
solid
It occurs more slowly because phosphorus rarely occurs as a gas.
