Cov orbitals uas lub plhaub sub-plhaub yog raws nraim ib nrab-sau los yog tag nrho yog ruaj khov vim yog cov symmetrical faib ntawm electrons … Thaum lub orbitals yog ib nrab puv los yog tag nrho ces tus naj npawb ntawm exchanges yog siab tshaj. Yog li ntawd, nws stability yog siab tshaj.
Vim li cas puv puv orbitals ruaj khov dua ib nrab?
- Peb paub tias ib nrab puv lossis puv puv atomic orbitals muaj qhov sib luag ntau dua li lwm yam kev teeb tsa hluav taws xob thiab qhov kev sib txuam no ua rau muaj kev ruaj ntseg ntau dua ntawm lub atom. … - Yog vim li cas tom qab stability ntawm ib nrab-sau thiab tag nrho cov electrons nyob rau hauv orbitals yog symmetry thiab pauv zog ntawm cov electrons
Vim li cas symmetry ua rau muaj kev ruaj ntseg?
Symmetry txhais tau hais tias muaj is vaj huam sib luag … Qhov ib nrab puv orbitals sib haum rau kev faib tawm ntawm tus nqi. Yog li s1, p3, d5 thiab f7 hluav taws xob configuration yuav ruaj khov thiab yuav muaj zog tsawg. Qhov no yog vim hais tias tag nrho cov orbitals nyob nrog sib npaug ntawm cov electrons.
Dab tsi orbitals ruaj khov tshaj?
Kev piav qhia: Ib nrab puv thiab puv puv orbitals yog qhov ruaj khov tshaj plaws.
Dab tsi yog ib nrab puv orbital?
Thaum muab cov electrons rau orbitals, ib lub tshuab hluav taws xob ua ntej nrhiav kom sau tag nrho cov orbitals nrog lub zog zoo sib xws (tseem hu ua degenerate orbitals) ua ntej ua ke nrog lwm cov hluav taws xob hauv ib nrab ntawm lub orbital. … Lub p orbitals yog ib nrab puv; muaj peb lub electrons thiab peb p orbitals.
