White phosphorus, yellow phosphorus, or simply tetraphosphorus (P 4) is an allotrope of phosphorus. It is a translucent waxy solid that quickly yellows in light (due to its photochemical conversion into red phosphorus ), [ 2 ] and impure white phosphorus is for this reason called yellow phosphorus.
It can cause “excruciating burns and lifelong suffering,” a Human Rights Watch spokesperson said.
White phosphorus, yellow phosphorus or simply tetraphosphorus (P 4) exists as molecules of four phosphorus atoms in a tetrahedral structure, joined by six phosphorus—phosphorus single bonds. [1] The free P 4 molecule in the gas phase has a P-P bond length of r g = 2.1994(3) Å as was determined by gas electron diffraction . [ 2 ]
White phosphorus is a highly efficient smoke-producing agent, reacting with air to produce an immediate blanket of phosphorus pentoxide vapour. Smoke-producing white phosphorus munitions are very common, particularly as smoke grenades for infantry , loaded in defensive grenade launchers on tanks and other armoured vehicles, and in the ...
The Pentagon recommended providing the white phosphorus shells to Ukraine as part of several aid packages, including a recent one, as a Presidential Drawdown Authority, according to the officials.
The Israeli military deployed white phosphorus, a controversial and lethal chemical substance, in its war against Hamas, putting civilians at risk of life-threatening burns, according to the Human ...
Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has an occurrence in the Earth's crust of about 0.1%, generally occurring as phosphate in minerals.
An Israeli Defence Forces spokesperson told the Post that the IDF use of the white phosphorous shells “complies and goes beyond the requirements of international law” and said Israel uses them ...
