Nitrogen dioxide is a chemical compound with the formula NO 2.One of several nitrogen oxides, nitrogen dioxide is a reddish-brown gas.It is a paramagnetic, bent molecule with C 2v point group symmetry.
The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
Nonmetals show more variability in their properties than do metals. [1] Metalloids are included here since they behave predominately as chemically weak nonmetals.. Physically, they nearly all exist as diatomic or monatomic gases, or polyatomic solids having more substantial (open-packed) forms and relatively small atomic radii, unlike metals, which are nearly all solid and close-packed, and ...
Twenty-three nonmetals. H is shown over Li and F; Germanium, As, Se, and Te are later referred to as metalloids; Sb is shown as a nonmetal but later referred to as a metal. They write, "Whilst these heavier elements [Se and Te] look metallic they show the chemical properties of non-metals and therefore come into the category of "metalloids" (p ...
Nonmetallic chemical elements are often described as lacking properties common to metals, namely shininess, pliability, good thermal and electrical conductivity, and a general capacity to form basic oxides. [8] [9] There is no widely accepted precise definition; [10] any list of nonmetals is open to debate and revision. [1]

Nonmetals have a wide range of properties, for instance the nonmetal diamond is the hardest known material, while the nonmetal molybdenum disulfide is a solid lubricants used in space. [47] There are some properties specific to them not having electrons at the Fermi energy.
Nitrite is an ambidentate ligand and can form a wide variety of coordination complexes by binding to metal ions in several ways. [2] Two examples are the red nitrito complex [Co(NH 3) 5 (ONO)] 2+ is metastable, isomerizing to the yellow nitro complex [Co(NH 3) 5 (NO 2)] 2+. Nitrite is processed by several enzymes, all of which utilize ...
