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 hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials.
C4H10(g) is about -126 kJ/mol C4H10(l) is about -147 kJ/mol

The standard SI unit for distance is the meter. If you add a standard prefix, like kilo, milli, etc., it can still be considered an SI unit.The standard SI unit for distance is the meter.

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.
Standard electrode potential is a redox electrode. This is the forms the basis of the thermodynamic scale.
Phosphorus forms individual P4 molecules. This is the standard form for white phosphorus.
The chemical symbol (not formula) of phosphorus is P.
The standard free energy of formation indicates the stability of a chemical compound. A lower value suggests greater thermodynamic stability, meaning the compound is more likely to form and exist in a given environment.
The amount of phosphorus in beer can vary depending on the type and brand of beer. On average, a standard 12-ounce serving of beer contains around 35-45 mg of phosphorus.
The standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials.
The standard free energy equation is G H - TS, where G is the standard free energy change, H is the standard enthalpy change, T is the temperature in Kelvin, and S is the standard entropy change. This equation is used to calculate the thermodynamic feasibility of a chemical reaction by comparing the standard free energy change to zero. If G is negative, the reaction is thermodynamically feasible and will proceed spontaneously. If G is positive, the reaction is not thermodynamically feasible and will not proceed spontaneously.
Solid.There are two allotopes of Phosphorus; Red Phosphorous and White Phosphorus, both are solids at room temperature under standard pressure.

Phosphorus can exist in any of these three forms, but is a waxy solid at standard conditions.Some Additional Information:White phosphorus is solid at temperatures below 44.2° C,gas at temperatures above 280.5° C, and liquid in between.
