Repulsion tshwm sim raws li txhua qhov kev sim ua kom khaws qhov chaw hauv lawv cov orbitals. Txawm hais tias lub zog quab yuam ntawm ob qho tib si, lawv kev sib txuas lub zog nce nrawmvim qhov kev sib cais tsawg zuj zus.
Puas repulsion nce lossis txo zog?
Raws li cov atoms nyob ze ib leeg, lawv sab nraud (valence) electrons cuam tshuam rau ib leeg, thiab lub zog ntawm lub zog no nce sai heev vim qhov kev ncua deb r txo… lub zog raws li cov atoms nyob ua ke yog hu ua steric repulsion los yog steric hindrance.
Vim li cas lub zog quab yuam ua rau muaj zog ntxiv?
Vim tias lub zog hluav taws xob ntawm qhov kev nyiam lossis kev tawm tsam ntawm lawv, ob qhov khoom siv hluav taws xob yuav txawv ntawm lub zog thaum peb hloov qhov kev ncua deb ntawm lawv. Tus nqi sib txawv (+ thiab -) nyiam, ib yam li lub ntiaj teb thiab txhua yam khoom, yog li lub zog muaj peev xwm nce ntxiv thaum peb siv zog los cais cov nqi
Lub zog muaj peev xwm cuam tshuam li cas rau kev nyiam thiab kev tawm tsam?
Peb paub tias los ntawm F=−dU/dx formula tias thaum lub zog txaus nyiam hauv qhov muaj peev xwm muaj zog nce ntxiv thiab thaum lub zog quab yuam, lub zog muaj peev xwm txo qis.
Vim li cas lub zog muaj peev xwm nce?
Qhov khoom hnyav dua thiab siab dua nws nyob saum av, qhov muaj peev xwm gravitational ntau dua nws tuav. Gravitational muaj peev xwm zog nce ntxiv raws li qhov hnyav thiab qhov siab nce. Lub zog muaj peev xwm yog lub zog uas khaws cia rau hauv ib yam khoom lossis khoom siv.
