Mapoka eNhangande Rudarikira

[chinjirudza | chinjirudza mabviro]

Zvichibva muGold Book ravo veIUPAC vanoti nhangande rudarikira inhangande ine gokerero-D (D-orbital) rakaperevedza pakuverengwa kwemhodzigetsi kana kuti nhangande inobuditsa manondanhuka aine gokerero-D rakaperevedza. Kutsetsenura kweduramazwi iri kunoreva kuti mapoka 3-11 ari pasi penhanhgande rudarikira. Mukutsetsura seizvi IUPAC yakasiya boka-12 kubva mubande renhangande rudarikira - zvoreva kuti zinc, cadmium and mercury dzakasiiwa kunze kwenhangande rudarikira.

Asi vamwe ana mhizhamushonga (chemist) vanochinjanisa zita renhangande dzeDandare-D (D-block) nenhanagande rudarikira, saka ava vanenge vachibatanidzira mapoka 3-12 senhangande rudarikira. Panhambo iyi, nhangande dzeboka 12 dzinobatwa nemutowo wakasarudzika wenhangande rudarikira unotendera kuti mhodzigetsi dzegokerero-D dzisagoverwa pakubhondha kwemitombo.
