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
Black or Red Black or Red Black or Red is an American card game, often played as a drinking game. In its most basic form it is one of the least complicated of drinking games.

Traditionally each player takes a turn in order, drawing a single card from the top of the deck. Before looking at the card, they must call either "Black" or "Red" indicating their guess as to the color of the card. If they guess correctly their turn is completed
