Red Phosphorusis an amorphous polymeric modification of the chemical element
phosphorus. Elemental phosphorus is readily oxidized and this high reactivity results in
hazardous properties of the material. However, red phosphorus is much less reactive and
even more less toxic than yellow (also called white) phosphorus1 (see appendix). Since red
phosphorus is a polymer, an exact molecular formula does not exist. The following
structure serves as an example to illustrate how each phosphorus atom is bonded to three others.

Is phosphorus a liquid or gas?
It is NEITHER at standard temperature and pressure. The pure element (which is practically never found in a pure form) is a white/yellow waxy solid, or a red amorphous solid, or a black powdery solid. But it does form both liquid and gaseous compounds at room temperature.
Does red phosphorus glow?
No only white phosphorus will
How is phosphorus used in the world?
Red Phosphorus is used on the tip of a match.
How does a phosphate group look like?
A phosphate is a modified triglyceride molecule- there are some good diagrams on google images- search for phospholipid. I'll try and describe it now: It has a head, two tails and a glycerol link. The head is a phosphate group- this is a phosphor atom bonded to 4 oxygen atoms. One of these connects to the glycerol molecule. This is 3 carbon atoms in a chain, each one is bonded to a different part- one to the head and one to each tail. Remaining bonds go to hydrogen atoms. The tails are fatty acid (lipid) groups. The tails are hydrophobic (do not dissolve in water), while the head is hydrophilic- dissolves in water. This means that the head is repelled from the tail. This is especially important in cell membranes- it forms a total barrier to water.
What is the chemical formula for red phosphorus?
P4
Why is red phosphorus classified an amorphous solid?
Red Phosphorusis an amorphous polymeric modification of the chemical elementphosphorus. Elemental phosphorus is readily oxidized and this high reactivity results inhazardous properties of the material. However, red phosphorus is much less reactive andeven more less toxic than yellow (also called white) phosphorus1 (see appendix). Since redphosphorus is a polymer, an exact molecular formula does not exist.

What is selenium standard state?
Solid state. Selenium is usually amorphous, brick-red powder.
What are properties of phosphorus?
1. Phosphorus is solid at room temperature.2. There are two forms - white and red. 3. Phosphorus is a reactive element.
What are three properties of phosphorus?
1. Phosphorus is solid at room temperature.2. There are two forms - white and red. 3. Phosphorus is a reactive element.
Is white phosphorus and phosphorus the samething?
Yes, white phosphorus is phosphorus. Phosphorus has several allotropes: white, red, violet, scarlet, black, and diphosphorus. While all are the same pure chemical the inter-atomic bonds are different, some allotropes are crystalline others amorphous, and chemical properties vary.white is poison and can ignite spontaneously.red is non-toxic and harder to ignite.etc.
Is phosphorus a solid liquid or gas in room temperature?
Solid.There are two allotopes of Phosphorus; Red Phosphorous and White Phosphorus, both are solids at room temperature under standard pressure.
What element's allotropes names are based upon their colors?
This may mean phosphorus which has a number of allotropes some of which are based on their colour White phosphorus - P4 red phosphorus - amorphous and three crystalline forms all polymeric in nature black phosphorus - three forms are known - again polymeric violet phosphorus (aqlso called Hittorfs phosphorus) As you can see some of the coloured forms exist in different crystalline forms and therefore colour alone is not a good indication of which allotrope is meant. The wikipedia artcle is inaccurate- if you can access Greenwood and Earnshaw "Chemistry of the e lements" that has a good write up.
What is the difference between red phosphorus and white phosphorus?
White phosphorus is obtained by roasting Calcium phosphate rocks and then reducing them using silica White phosphorus reacts with air vigorously that is it burns instantly in presence of oxygen and show phophorescence property ( it emits bright luminous green light in dark in prsence of small amount of oxygen ) , hence it is stable below 125'C and red phosphorus is stable above 125'C. If you heat white phosphorus upto 125'C in absence of air you get red phosphorus. White phosphorus has 4 atoms of P linked in tetrahedral shape, where as red phosphorus have amorphous network arrangement hence red phosphorus is more stable. White P is soluble in carbon di sulfide and small amount in water, but red P is not soluble in both water and carbon disulfide. white P is used in explosives, incendiaries, bullets etc
Solid samples of the element phosphorus can be white black or red in color The variations in color are due to different?
molecular structures
What is the state of the element phosphorous at room temp?
Phosphorus is solid at room temperature. That said, phosphorus is an element that can take different solid forms, depending upon how it was prepared and other factors. These different forms are called "allotropes".So a room temperature sample of phosphorus could be the common red phosphorus, used to make matches and road flares; the poisonous waxy white phosphorus, which is used to make incendiary bombs; or the rare purple/black phosphorus. You can see pictures of all three allotropes by googling "phosphorus".
