Can phosphorus be posion?
White phosphorus is very dangerous and not just because it is poisonous. Red phosphorus is considered less poisonous.
What is th oxidation number of phosphorus in red phosphorus?
The oxidation number of phosphorus in red phosphorus is 0. This is because in red phosphorus, phosphorus is in its elemental form, and the oxidation number of any element in its elemental form is always 0.
Why is phosphorus considered a limiting nutrient in ecosystems?
Phosphorus is considered a limiting nutrient in ecosystems because it is essential for plant growth and is often in short supply in the environment. Without enough phosphorus, plants cannot grow properly, which can limit the overall productivity of the ecosystem.
What kind of nutrient are ironcalcium and phosphorus?
Iron is a mineral, calcium and phosphorus are generally considered salts (though salts are also minerals).
How poisonous is red phosphorus?
As compared to white phosphorus, it is not so dangerous, as it is not poisonous and it does ignite spontaneously in air, if temperature is below 260 ºC. So, it is relatively stable and less reactive than white phosphorus.
Is P4 elemental form?
No, phosphorus (P4) is a molecular form composed of four phosphorus atoms bonded together. It is not considered an elemental form as phosphorus is typically found in nature as phosphate minerals.
Is P part of inorganic molecule?
Phosphorus (P) is considered as an element.
What is phosphorus' state of matter?
Phosphorus exists in multiple allotropes, with the most common being white phosphorus, which is a solid. Red phosphorus is another common form, which is also a solid. Both white and red phosphorus are considered non-metallic elements in solid form.
What are phosphorus's common isotopes?
Phosphorus is considered practically monoisotopic: P-31; radioactive isotopes P-32 and P-33 exist only in traces.
Is phosphorus a conductor or a insulator?
Phosphorus is typically considered an insulator because it does not conduct electricity well. However, when doped with certain impurities, it can become a semiconductor with conductive properties.
Is phosphorus hard or soft?
Phosphorus can exist in several allotropes, each with different properties. The most common forms are white phosphorus, which is soft and waxy, and red phosphorus, which is more stable and has a harder, more brittle texture. Black phosphorus, another allotrope, has a layered structure and is considered the least reactive and most stable form. Overall, phosphorus can be classified as either hard or soft depending on its allotrope.
Is the phosphorus cycle open or closed?
The phosphorus cycle is considered a closed system because phosphorus does not have a gaseous phase and tends to remain in the solid or dissolved form in ecosystems. This means that phosphorus is continuously recycled within ecosystems through processes like weathering, uptake by plants, and decomposition.
