Mayelana nalolu hlelo lokusebenza

I-Quantum mechanics inkambu ethokozisayo esisiza ukuthi siqonde ukuziphatha kwento namandla ezingeni le-microscopic. Omunye wemiqondo ebaluleke kakhulu ku-quantum mechanics umqondo we-athomu orbitals.

I-atomic orbital iwumsebenzi wezibalo ochaza amathuba okuthola i-electron endaweni ethile ezungeze inucleus ye-athomu. I-electron ngayinye e-athomu ingachazwa ngesethi eyingqayizivele yezinombolo ezine ze-quantum, ezinquma izinga layo lamandla, umfutho we-angular, umzuzu kazibuthe, kanye ne-spin.

Ukuma kwe-athomu ngayinye ye-athomu kungavezwa ngokunembile kusetshenziswa ifomula ebizwa ngokuthi i-spherical harmonics, edala ukumelelwa okubonakalayo kwendawo okungenzeka ye-electron ezungeze i-nucleus. Lezi izethulo zivame ukuboniswa njengochungechunge lwamachashazi, ngalinye limelela indawo okungenzeka ibe khona lapho i-electron ingaba khona.

Ithiyori ye-VSEPR (Valence Shell Electron Pair Repulsion), ngakolunye uhlangothi, iyimodeli esetshenziselwa ukubikezela i-geometry yama-molecule ngokusekelwe ekuhlelweni kwama-electron kumagobolondo awo e-valence. Ngokwale mbono, ama-electron egobolondweni le-valence ye-molecule ayaxoshana, futhi ukwenyanya kwawo kunquma ukuma kwe-molecule.

Imodeli ye-VSEPR ibikezela uchungechunge lwezimo zamangqamuzana, okuhlanganisa i-linear, trigonal planar, i-tetrahedral, i-trigonal bipyramidal, ne-octahedral. Lezi zimo zingasetshenziswa ukubikezela izakhiwo zomzimba nezamakhemikhali ze-molecule, njenge-polarity kanye nokusebenza kabusha.

Lolu hlelo lokusebenza luzokunikeza le mininingwane ethakazelisayo mayelana nemvelo yokuthi ama-athomu nama-molecule aziphatha kanjani emhlabeni wangempela.

Yini entsha

We are excited to announce that we have added HOMO/LUMO support and some iconic organic compounds! With this update, you can now explore the structures and properties of benzene and methanol, two of the most important organic compounds in chemistry.
