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.
What reactive non metal is a solid that comes in 3 forms?
Phosphorus is a reactive non-metal that exists in three main forms: white phosphorus, red phosphorus, and black phosphorus. Each form has different physical and chemical properties, with white phosphorus being the most reactive and toxic.
What chemical is phosphorus 4 oxygen 10?
The chemical formula for phosphorus pentoxide is P4O10. It is a white solid compound commonly used as a desiccant and dehydrating agent.
What is the chemical formula for phosporus?
Phosphorus may rarely be seen as P, but it will usually be seen as white or red phosphorus, both of which are P4. White P4 is a tetrahedral structure. Red P4 is a chain-like structure, where one of the bonds from white P4 is broken and joined with a neighboring P4.
Is P4 the chemical formula of phosphorous?
No, P4 is not the chemical formula of phosphorous. The chemical formula of phosphorous is P. P4 represents a molecule of elemental phosphorus, which consists of a tetrahedral arrangement of four phosphorus atoms.
Is white phosphorus that glows when exposed to air a chemical change or a physical change?
White phosphorus that glows when exposed to air is a chemical change. This phenomenon occurs because white phosphorus undergoes a chemical reaction with oxygen in the air to form phosphorus oxide, releasing energy in the form of light.
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.
