Phosphorus does not have inherent color properties. In compounds, phosphorus can exhibit a variety of colors depending on its oxidation state and the other elements present in the compound. Some common colors of phosphorus compounds include white, yellow, red, and black.
Phophorus, whose allotropes are red phosphorus, white phosphorus , black phosphorus, violet phosphorus
White phosphorus is a very reactive chemical because of its structure. When it is heated some, it can react with oxygen to create phosphorus pentoxide (it is in this exothermic reaction that you see the glow). So it is indeed a chemical change.
No they can not change colors
Burning of anything is a chemical change. Combustion (burning) is a chemical reaction; it is simply where oxygen is added to, for example, an element, and turns it into an oxide. Burning phosphorus would result in phosphorus oxide. P + O2 --> P4010
The allotropes of selennium and phosphorus
Phosphorus can be many colors. It can be red, white or even bronze.
uh
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.

A homophone for "change colors" is "exchange collars."
Because they need to hide there self from enimies.
