What type of solid is phosphorus?
Case Study: Phosphorus White phosphorus forms molecular crystals composed of tetrahedral P4 molecules.
A molecular solid, white phosphorus has a relatively low density of 1.82 g/cm3 and melting point of 44.1 °C; it is a soft material which can be cut with a knife..
Is red phosphorus illegal?
Iodine/red phosphorus. The principal chemicals are ephedrine or pseudoephedrine, iodine, and red phosphorus. However, it is illegal to import, export, purchase, or sell iodine crystals in the United States if they are used or intended to be used in the production of methamphetamine.
What are the symptoms of low phosphorus?
When symptoms do occur, they can include:muscle weakness.fatigue.bone pain.bone fractures.appetite loss.irritability.numbness.confusion.More items…
Where is most phosphorus found on Earth?
The largest source or reservoir of phosphorus on earth is sediments, typically sedimentary rocks. There is a significant amount of phosphorous is ocean sediments as well. Phosphorous can also be found in plants, animals, and the soil.
Which phosphorus is more reactive?
White phosphorusWhite phosphorus is the least stable, the most reactive, the most volatile, the least dense, and the most toxic of the allotropes. It gradually changes to red phosphorus, a transformation accelerated by light and heat.
Is Phosphorus a solid or liquid?
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Phosphorus is classified as an element in the ‘Non-Metals’ section which can be located in groups 14,15 and 16 of the Periodic Table.
What does phosphorus look like?
Phosphorus is white, red, or black in color. When phosphorus is combined with certain other elements, it glows in the dark. Phosphorus can smell like garlic.
How can phosphorus kill you?
Phosphorus is an excellent candidate for a poison blog as there are a surprising number of ways it can kill you. … Phosphorus is an essential part of life. When combined with oxygen to make phosphates, it holds our DNA together, makes our bones strong and carries out fundamental chemical reactions within our cells.
What happens when phosphorus is too high?
High phosphorus levels can cause damage to your body. 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.
Is Black phosphorus dangerous?
Red phosphorus is not poisonous and is not as dangerous as white phosphorus, although frictional heating is enough to change it back to white phosphorus. … Black phosphorus is the least reactive form of phosphorus and has no significant commercial uses.
What does phosphorus do to the human body?
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.
Why is phosphorus called the devil’s element?
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. Like other nonmetals, pure phosphorus assumes markedly different forms.
What household items have phosphorus?
Sources of PhosphorusFood and Drug Industry. Phosphates are added to lunch meats, cheese, canned tuna, non-dairy coffee whiteners and multi-vitamins. … Detergents. … Dishwasher Detergents and Household Cleaners. … Agriculture. … Car Washing. … Wastewater. … Storm Water. … Lawn and Garden Fertilizers.More items…
What foods are high in phosphorus?
Phosphorus is found in high amounts in protein foods such as milk and milk products and meat and alternatives, such as beans, lentils and nuts. Grains, especially whole grains provide phosphorus. Phosporus is found in smaller amounts in vegetables and fruit.
Is white phosphorus banned?
Because it has legal uses, white phosphorus is not banned as a chemical weapon under international conventions. … “Infection is common and the body’s absorption of the chemical can cause serious damage to internal organs, as well as death,” Human Rights Watch says.
Why is phosphorus written p4?
Phosphorus can form a P4 white phosphorus tetrahedron because it can form three bonds, while sulfur can only form two bonds. Therefore sulfur forms rings and chains only. The most stable allotrope of phosphorus, red phosphorus, is a cross-linked, polymeric chain of atoms.
What is phosphorus used in?
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).
Why is phosphorus important for life?
Phosphorus is an essential element which is contained in many cellular compounds, such as DNA and the energy carrier ATP. All life needs phosphorus and agricultural yields are improved when phosphorus is added to growing plants and the diet of livestock.
Which phosphorus is most stable?
Black phosphorusBlack phosphorus is the thermodynamically stable form of phosphorus at room temperature and pressure, with a heat of formation of -39.3 kJ/mol (relative to white phosphorus which is defined as the standard state). It was first synthesized by heating white phosphorus under high pressures (12,000 atmospheres) in 1914.
Why is phosphorus solid at room temperature?
In phosphorus, the atoms do not pair up, they bond to their neighboring atoms, thus forming a network of bonding that holds the atoms together into a solid. … Phosphorus atoms are much larger and thus less active and closer together at room temperature allowing them to form a solid structure.
