What are the main uses of phosphorus?
Uses of Phosphorus
Phosphorus is used in the manufacture of safety matches (red phosphorus), pyrotechnics and incendiary shells. Phosphorus is also used in steel manufacture and in the production of phosphor bronze. Phosphates are ingredients of some detergents. Phosphorus is used to make light-emitting diodes (LEDs).
How do humans use phosphorus?
Function. The main function of phosphorus is in the formation of bones and teeth. It plays an important role in how the body uses carbohydrates and fats. It is also needed for the body to make protein for the growth, maintenance, and repair of cells and tissues.
Is Phosphorus-32 Harmful?
Phosphorus-32 is an energetic beta emitter which can penetrate up to 0.8 cm into living skin tissue. Therefore, this isotope poses an external (skin) dose hazard to persons as well as a potential internal hazard.
What’s the half-life of phosphorus 31?
Phosphorus
| Mass Number | Half-life | Decay Mode |
|---|---|---|
| 30 | 2.498 minutes | Electron Capture |
| 31 | STABLE | – |
| 32 | 14.262 days | Beta-minus Decay |
| 33 | 25.35 days | Beta-minus Decay |
What is phosphorus-32 half-life?
Phosphorus-32 is a commonly used radionuclide with a half-life of 14.3 days, emitting beta particles with a maximum energy of 1.71 MeV (Million Electron Volts).
What are the two major human uses of phosphorus?
It is essential for the creation of DNA, cell membranes, and for bone and teeth formation in humans. It is vital for food production since it is one of three nutrients (nitrogen, potassium and phosphorus) used in commercial fertilizer.
What are 5 physical properties of phosphorus?
Properties: The melting point of phosphorus (white) is 44.1°C, boiling point (white) is 280°C, specific gravity (white) is 1.82, (red) 2.20, (black) 2.25-2.69, with a valence of 3 or 5. There are four allotropic forms of phosphorus: two forms of white (or yellow), red, and black (or violet).
How does phosphorus look like?
Phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.
What are the signs of phosphorus deficiency?
Symptoms of phosphorus deficiency include loss of appetite, anxiety, bone pain, fragile bones, stiff joints, fatigue, irregular breathing, irritability, numbness, weakness, and weight change. In children, decreased growth and poor bone and tooth development may occur.
What happens if you eat too much phosphorus?
Extra phosphorus causes body changes that pull calcium out of your bones, making them weak. High phosphorus and calcium levels also lead to dangerous calcium deposits in blood vessels, lungs, eyes, and heart. Over time this can lead to increased risk of heart attack, stroke or death.
What foods to avoid if phosphorus is high?
High Phosphorus Foods to Avoid or Limit:
- Dairy foods.
- Beans.
- Lentils.
- Nuts.
- Bran cereals.
- Oatmeal.
- Colas and other drinks with phosphate additives.
- Some bottled ice tea.
What is phosphorus-32 half life?
Phosphorus-32 is a commonly used radionuclide with a half-life of 14.3 days, emitting beta particles with a maximum energy of 1.71 MeV (Million Electron Volts).
When a sample of phosphorus-32 is placed 1 cm from the detector?
When a sample of phosphorus-32 (a beta-emitter used to treat leukemia and pancreatic cancer) was placed 1 cm from the detector, the intensity of its radiation was measured to be 491 counts per second.
What is the difference between 31p and 32p?
Phosphorus-32 is known as a radioactive isotope of the phosphorus element. The nucleus of this isotope has 15 protons and 17 neutrons. There is also Phosphorus-31 which is the most common isotope of phosphorus. Therefore, the difference between them is one neutron more than the other.
What’s the function of phosphorus?
Function. The main function of phosphorus is in the formation of bones and teeth. It plays an important role in how the body uses carbohydrates and fats. It is also needed for the body to make protein for the growth, maintenance, and repair of cells and tissues.
How long does it take for half the amount of phosphorus to decay?
The half-life of phosphorus-32 is 14 days. After 14 days, half of the original amount of phosphorus-32 has decayed, so only half remains. After another 14 days, half of the remaining amount (or a quarter of the original amount) is still left, and so on.
How much does phosphorus cost?
Cost of Phosphorus
The price of pure phosphorus is $0.3 per gram.
Is Phosphorus-31 stable or unstable?
Phosphorus-31 is naturally occuring and is stable(2). Phosphorus-26 through 30 and phosphorus-32 through 46 are artificially produced and are radioactive(2).
Why is phosphorus called the devil’s element?
Phosphorus was discovered in 1669 by Hennig Brand in Germany. … Only the white allotrope or form of phosphorus glows in the dark. Some texts refer to phosphorus as the « Devil’s Element » because of its eerie glow, tendency to burst into flame, and because it was the 13th known element.
How much phosphorus should I take daily?
The Food and Nutrition Board of the Institute of Medicine recommends a diet with 700 mg/day of phosphorus in healthy people, and 1250 mg/day in children and pregnant women [14].
What are the symptoms of phosphorus deficiency?
Some medications can cause phosphorus levels to drop, including some antacids and diuretics (water pills). Symptoms of phosphorus deficiency include loss of appetite, anxiety, bone pain, fragile bones, stiff joints, fatigue, irregular breathing, irritability, numbness, weakness, and weight change.
