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.
The chemical symbol (not formula) of phosphorus is P.

The standard state of magnesium is solid.
Zero. Phosphorus will not trade electrons with itself.

A phosphorus standard is a set limit established by regulatory bodies on the amount of phosphorus allowed in various products or materials, such as water, fertilizers, or food. It helps to regulate phosphorus levels to prevent environmental pollution and promote public health.
Phosphorus forms individual P4 molecules. This is the standard form for white phosphorus.

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 is typically in a solid state at room temperature. There are different allotropes of phosphorus, with the most common form being white phosphorus, which is a waxy solid.
At normal temperatures, phosphorus is a solid.
gas
Phosphorus has three unpaired electrons in its ground state.
Phosphorus exists in multiple allotropes, with the most common being white phosphorus, which is a solid. Red phosphorus is another common form, which is also a solid. Both white and red phosphorus are considered non-metallic elements in solid form.
