Allotropes of phosphorus diphosphorus molecule begins to dissociate into atomic phosphorus. P nanorod polymers were isolated from CuI-P complexes using low temperature treatment. Red/brown phosphorus was shown to be stable in air for several weeks and have significantly different properties from red phosphorus. Electron microscopy showed that red/brown phosphorus forms long, parallel nanorods with a diameter between 3.4 Å and 4.7 Å. Allotropes of phosphorus Elemental phosphorus can exist in several allotropes, the most common of which are white and red solids. Solid violet and black allotropes are also known. Gaseous phosphorus exists as diphosphorus and atomic phosphorus. White phosphorus, yellow phosphorus or
Viola pedata typical garden environments because it does not tolerate rich, organic garden soils and excess moisture. Viola pedata Viola pedata, the birdsfoot violet, bird's-foot violet, or mountain pansy, is a violet native to sandy areas in central and eastern North America. Two primary color forms exist, "Viola pedata" var. "lineariloba" ("concolor"), which is a solid pink-lilac-lavendar color, and var. "pedata" ("bicolor"), in which the superior petals are a deep red-purple and the lateral and interior petals are similar to the concolor variety. Less common is "Viola pedata" var. "linearloba" forma "alba", which is a white flowered form. Birdsfoot violet favors well
