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.

Vim li cas thiaj ua rau lub sijhawm nyob ruaj khov?
Lub Sijhawm series nyob ruaj khov yog tias lawv tsis muaj qhov sib txawv lossis raws caij nyoog. Cov ntaub ntawv txheeb cais suav nrog lub sijhawm ua haujlwm zoo ib yam li lub sijhawm, zoo li qhov nruab nrab lossis qhov sib txawv ntawm qhov kev soj ntsuam.
Vim li cas tiv thaiv kev ua kom ruaj khov dua?
Raws li nws txuas ntxiv tig, nws ntsib qhov tsis zoo eclipsed conformation uas ib pawg methyl eclipses hydrogen. Raws li kev sib hloov txuas ntxiv mus, cov molecule los mus rau kev tiv thaiv conformation, uas yog qhov ruaj khov tshaj plaws vim cov neeg hloov pauv tau staggered thiab cov methyl pawg nyob deb ntawm ib leeg li sai tau Dab tsi ua rau kev sib haum xeeb ruaj khov?
Vim li cas lyophilic sols ruaj khov dua?
Lyophilic sol yog ruaj khov dua li lyophobic sol. Qhov kev ruaj ntseg ntawm lyophilic sols yog tshwm sim los ntawm ob yam, qhov muaj tus nqi thiab kev daws ntawm colloidal particles… . Vim li cas Lyophilic sols ruaj khov dua li Lyophobic sols?
Vim li cas chelate compounds ruaj khov dua?
Chelating ligand tuaj yeem tsim lub nplhaib nrog lub hauv paus hlau. Yog li nws muaj peev xwm tswj tau electron nrog rau hauv lub nplhaib. Vim nws muaj ntau lub zog ntawm kev nyiam ntawm nruab nrab hlau ion chelating tus neeg sawv cev, yog li ntawd, lawv ruaj khov dua .
Puas yog riam phom nuclear ruaj khov lossis tsis muaj kev ruaj ntseg?
Txoj kev tshawb fawb tau txiav txim siab tias thaum riam phom nuclear txhawb kev ruaj ntseg, thiab tiv thaiv kev ua tsov rog loj, lawv ib txhij tso cai rau kev tsis sib haum xeeb qis dua . Puas yog riam phom nuclear puas ncaj ncees? Kev txwv tsis pub muaj riam phom nuclear yog kev ncaj ncees rau tib neeg, kev ncaj ncees, thiab kev cai lij choj.
