Siyini isakhiwo samakhemikhali?
Context:Ukuhlonza ukwakheka kwamakhemikhali kuhlanganisa ukuba usokhemisi achaze ukwakheka kwamangqamuzana futhi, lapho kungenzeka futhi kudingekile, ukwakheka kwama-electron e-molecule okuhlosiwe noma enye into eqinile. I-molecular geometry ibhekisela ekuhlelekeni kwe-athomu ku-molecule kanye nezixhumanisi zamakhemikhali ezigcina ama-athomu ndawonye futhi zingabonakaliswa ngokusebenzisa amafomula ezakhiwo kanye namamodeli wamangqamuzana; izincazelo eziphelele zesakhiwo se-elekthronikhi zifaka ukucacisa umsebenzi wama-molecule we-molecule. Ukunqunywa kwesakhiwo kungasetshenziswa ezinhlotsheni ezihlukahlukene zamangqamuzana alula kakhulu (isib., i-diatomic oxygen noma i-nitrogen) kuya kwalawo ayinkimbinkimbi kakhulu (isib., njengamaprotheni noma i-DNA).
