The glow of white phosphorus in the dark is a result of a chemical reaction, specifically the oxidation of phosphorus. When exposed to oxygen, white phosphorus reacts and emits light due to the energy released during the reaction. This phenomenon is not a physical property like fluorescence, but rather a result of the chemical transformation taking place.

Is white phosphorus that glows when exposed to air a chemical change or a physical change?

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.


White phosphorous glows in the dark is it a chemical properties or physical?

This is a physical property because it describes a characteristic that can be observed without changing the composition of the substance. The ability of white phosphorus to glow in the dark is due to its property of emitting light when exposed to oxygen.


Is phosphorus invisible?

Phosphorus is not invisible. It is a chemical element that is typically found in a solid state (white phosphorus) or as a part of various compounds. White phosphorus appears colorless or slightly yellow in daylight and glows green in the dark.


Its white variety glows upon exposure to oxygen?

The substance you're referring to is phosphorus. White phosphorus is very reactive and glows in the dark due to its exposure to oxygen, a process known as chemiluminescence. This unique property makes it useful in military applications for incendiary devices and smoke screens.


What unusual or special properties does phosphorus have?

Phosphorus has the property of existing in various allotropes, such as white, red, and black phosphorus, each with different physical and chemical properties. It is also an essential element for life, being a key component of DNA and RNA. Additionally, phosphorus can exhibit luminescence when exposed to ultraviolet light, making it useful in applications such as inorganic LEDs.


Is White phosphorous ignites easily a physical change?

Yes, white phosphorus igniting is a physical change because it involves a change in the physical state of the substance (from solid to gas) without altering its chemical composition.


What are all the elements that make up a phosphorus?

Phosphorus is a chemical element with symbol P and atomic number 15. It is a nonmetal with multiple allotropes, including white phosphorus, red phosphorus, and black phosphorus. Each allotrope has different physical and chemical properties.


What are facts about phosphorus Like stuff that most people dont know?

this element glows from white phosphorus and is an allotropeit comes in colorless waxy whiyt


What is the description of phosphorus?

It glows in the dark, colorless, red, silver, white, tasteless, garlic like odor.


What are three allotropes of phosphorus how are they different?

The three allotropes of phosphorus are white phosphorus, red phosphorus, and black phosphorus. White phosphorus is a highly reactive and toxic form that glows in the dark, red phosphorus is more stable and less reactive, and black phosphorus has a layered structure similar to graphite and exhibits semiconducting properties.


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.


What is the temperature that phosphorus become solid?

Phosphorus is a solid chemical element up to 44,2 0C - the melting point of the allotrope white phosphorus.
