How many atoms of phosphorus are present in 3.65 moles of phosphorus triiodide?
it is 20456678
What is phosphorus sulphate used for?
There are many uses of phosphorus such as: 1. Phosphates are used to make special glass which is used for sodium lamps 2. Plants needs phosphorus for nutrition. Thus, it is added in fertilizers; 3. Radioactive isotopes of phosphorus are used as radioactive tracers; 4. China ware are made up of calcium phosphate 5. Matchstick strikers are made up of phosphorus 6. Incendiary Bombs, Tracer Ammunition, and Smoke Screen are made up of white phosphorus 7. One compound of phosphorus called tributylphosphate is used for extracting uranium 8. DNA and RNA makes use of phosphorus 9. Phosphorus is also used in manufacturing steel 10. It is used as detergent (Sodium tripolyphosphate) 11. Used for manufacturing fertilizers, toothpaste, food additives and pesticides (0ther compounds of Phosphorus)
How many core electrons are in phosphorus?
Phosphorus has 15 electrons per atom. Out of those, 5 are valence electrons. That means phosphorus has 10 core electrons.
How many protons and electrons are in phosphorus?
15 electrons and 15 protons
How many phosphorus atoms are there in 1.0 gram phosphorus?
1 gram phosphorus (1mol P/30.97 grams)(6.022 X 10^23/1mol P) = 1.9 X 10^22 atoms of phosphorus
What are three isotopes of phosphorus?
The principal natural isotope of phosphorus is P-31; isotopes P-32 and P-33 are only in traces and unstables.
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 there any isotopes in phosphorus?
Yes, phosphorus has several isotopes. The main isotopes are phosphorus-31, which is stable, and phosphorus-32, a radioactive isotope commonly used in research and medicine.
What group and period does phosphorus belong to?
Phosphorus belongs to Group 15 (or Group VA) and Period 3 of the periodic table.
Why does both isotopes of phosphorus have identical chemical properties?
All isotopes of a substance are chemically the same. It is their physical properties which are different.
How is phosphorus P-31 and P-32 similar?
Phosphorus-31 and phosphorus-32 are both isotopes of the element phosphorus, differing only in the number of neutrons they possess. They share similar chemical properties due to having the same number of protons, but phosphorus-32 is radioactive with a half-life of around 14 days, making it useful in biological research and medicine.
What isotope iodine iron phosphorus radium has the longest half-time?
Phosphorus, iron, and iodine all have at least one isotope that is stable, and any of these would do for the longest half life. In fact, the radioactive isotopes of phosphorus are all synthetic, so radioactive phosphorus is not found in nature.
What is the atomic number of the unstable isotopes phosphorous 32?
15, same as any other phosphorus isotope.
Does interstitial radiation use phosphorus?
Yes, interstitial radiation therapy can use radioactive isotopes of phosphorus, such as phosphorus-32, as a treatment for certain cancers. These radioactive sources are implanted directly into or near the tumor to deliver localized radiation therapy.
What element has 14 or 15 neutrons?
The Most common isotopes of elements with 14 & 15 neutrons are, respectively, silicon & phosphorus.
List the isotopes used in agriculture?
Isotopes commonly used in agriculture include carbon-14 for carbon dating of soil and organic matter, nitrogen-15 for studying nitrogen uptake in plants, phosphorus-32 for tracing phosphorus movement in soil and plants, and potassium-40 for studying potassium uptake in plants.
Describe one way that radioactive isotopes have been used in agriculture?
Radioactive isotopes have been used in agriculture to measure uptake of nutrients by plants. For example, radioactive phosphorus can be used to track the movement of phosphorus in soil and its absorption by plants, providing valuable insights into nutrient cycling and plant nutrition.
