Phosphorus mononitride is an inorganic compound with the chemical formula P N. Containing only phosphorus and nitrogen, this material is classified as a binary nitride. From the Lewis structure perspective, it can be represented with a P-N triple bond with a lone pair on each atom. It is isoelectronic with N 2, CO, P 2, CS and SiO.
Phosphorus nitride refers to several chemical compounds of phosphorus and nitrogen: Phosphorus mononitride; Tetraphosphorus hexanitride; Triphosphorus pentanitride
Phosphorus monoxide is an unstable radical inorganic compound with molecular formula P O. [2] Phosphorus monoxide is notable as one of the few molecular compounds containing phosphorus that has been detected outside of Earth. Other phosphorus containing molecules found in space include PN, PC, PC 2, HCP and PH 3.
Phosphorus dioxide (PO 2) is a gaseous oxide of phosphorus. It is a free radical that plays a role in the chemiluminescence of phosphorus and phosphine. [1] It is produced when phosphates are heated to high temperatures. [2] In the ground state the molecule is bent, like nitrogen dioxide, but there is an excited state that is linear. [1]
Triphosphorus pentanitride is an inorganic compound with the chemical formula P 3 N 5. Containing only phosphorus and nitrogen, this material is classified as a binary nitride. While it has been investigated for various applications this has not led to any significant industrial uses.
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.
Protactinium forms mixed binary oxides with various metals. With alkali metals A, the crystals have a chemical formula APaO 3 and perovskite structure, or A 3 PaO 4 and distorted rock-salt structure, or A 7 PaO 6 where oxygen atoms form a hexagonal close-packed lattice. In all these materials, protactinium ions are octahedrally coordinated.
Np 3 P 4 can be created by reacting neptunium metal with red phosphorus at 740 °C in a vacuum and then allowing any extra phosphorus to sublimate away. The compound is non-reactive with water but will react with nitric acid to produce Np(IV) solution. [54] [55] [56] Three neptunium arsenide compounds have been prepared, NpAs, NpAs 2, and Np 3 ...
