Exempel på hur man kan använda PNICTOGEN i en mening

• A stable binary hydride and the simplest pnictogen hydride, ammonia is a colourless gas with a distinctive pungent smell.
• Phosphorus is classified as a pnictogen, together with nitrogen, arsenic, antimony, bismuth, and moscovium.
• It is a member of the 7th period and is placed in group 15 as the heaviest pnictogen, although it has not been confirmed to behave as a heavier homologue of the pnictogen bismuth.
• This flammable, pyrophoric, and highly toxic pnictogen hydride gas is one of the simplest compounds of arsenic.
• In chemistry, an onium ion is a cation formally obtained by the protonation of mononuclear parent hydride of a pnictogen (group 15 of the periodic table), chalcogen (group 16), or halogen (group 17).
• The σ-hole concept readily extends to pnictogen, chalcogen and aerogen bonds, corresponding to atoms of Groups 15, 16 and 18 (respectively).
• Hydrogen is fitted in to be less electronegative than any chalcogen and more electronegative than any pnictogen.
• Bismuth pentafluoride is the most reactive of the pnictogen pentafluorides and is an extremely strong fluorinating agent.
• These are generally less stable than the trihydrides, commonly decomposing to the trihydride and the pnictogen involved.
• Nontrigonal pnictogen compounds refer to tricoordinate trivalent pnictogen (phosphorus, arsenic, antimony and bismuth: P, As, Sb and Bi) compounds that are not of typical trigonal pyramidal molecular geometry.
• Like its pnictogen congeners, hexafluoroarsenate is a noncoordinating anion, a counterion used to stably store extremely reactive cations.
• Neptunium chalcogen and pnictogen compounds have been well studied primarily as part of research into their electronic and magnetic properties and their interactions in the natural environment.
• Interaction types that are broadly accepted as subclasses of the sigma hole interaction include tetrel bonding (in which a sigma hole resides on an atom of group IV), pnictogen bonding (group V), chalcogen bonding (group VI),.
• As noted above with the aza- and phosphatetrahedranes, the change in pnictogen electronegativity changes the interaction between the Pn atom and the C-C-C ring.
