zijn ook bekend als <i>pnicogenen</i> of <i>pnictogenen</i>. Tegenwoordig wordt de IUPAC naam <i>stikstofgroep</i> gebruikt. Deze elementen kenmerken zich doordat de buitenste p-subschil 3 elektronen bevat. De stikstofgroep is de enige groep in het <a href="/wiki/Periodiek_systeem" title="Periodiek systeem">periodiek systeem</a> waarbij de overgangen van metaal naar niet-metaal en van zuurvormend en basevormend zo duidelijk naar voren komt. </p><p>Het lichtste element uit deze groep (<a href="/wiki/Stikstof_(element)" title="Stikstof (element)">stikstof</a>) is een niet-metaal en een matig sterke oxidator in reacties met metalen. Met bijvoorbeeld <a href="/wiki/Magnesium" title="Magnesium">magnesium</a> vormt het een <a href="/wiki/Nitride" title="Nitride">nitride</a>. Aan het andere uiterste van de stikstofgroep is <a href="/wiki/Bismut" title="Bismut">bismut</a> te vinden; een element dat duidelijk een metaal is. </p><p>Stikstof en <a href="/wiki/Fosfor" title="Fosfor">fosfor</a> zijn biologisch van groot belang omdat ze deel uitmaken van eiwitten en nucleïnezuren. </p><p>De elementen in de stikstofgroep zijn in het periodiek systeem hieronder
