4. Umehluko phakathi kwenkolelo-mbono kaRutherford ye-athomu kanye nenkolelo-mbono kaBohr ye-athomu...
A. Ku-athomu kaBohr, i-spectrum ye-athomu ye-hydrogen ayifani, kanti ku-athomu kaRutherford iyaqhubeka.
B. Ku-athomu kaBohr, ama-electron azungeza i-nucleus ngenkathi ekhipha amandla, kanti ku-athomu kaRutherford awakhiphi amandla.
C. Ku-athomu kaBohr, ama-electron ajikeleza ku-orbit engashintshi, kanti i-Rutherford isesimweni se-parabolic orbit.
D. Ku-athomu kaBohr, imijikelezo emile ayinawo amandla, kanti ku-Rutherford, yonke imijikelezo inamandla.
E. Ku-athomu kaBohr, ama-electron awakwazi ukushintsha imijikelezo, kanti ku-Rutherford, ama-electron angashintsha imijikelezo.

5. Naka izitatimende ezilandelayo mayelana nethiyori ye-athomu!
(1) Umjikelezo wama-electron azungeze i-nucleus uhlala ungaguquguquki.
(2) Ama-electron awakhiphi amandla esimweni somhlaba.
( 3) I-spectrum yokukhishwa kwama-athomu e-hydrogen iyaqhubeka.
(4) Uma ama-electron eshintsha izindlela, inani lama-photon lizokhishwa/limuncwe.
Isitatimende esifanele esingenhla mayelana nemodeli ye-athomu ye-Bohr sithi…
A. (1), (2), kanye (3)
B. (1) kanye (3) kuphela
C. (1), (3), kanye (4) kuphela
D. (2) kanye no-(4) kuphela

Isitatimende 1 siyiqiniso, umjikelezo wama-electron uhlala uzinzile kodwa ama-electron angahamba esuka kwenye indlela (orbit) aye kwenye.
Isitatimende sesi-2 siyiqiniso, hhayi nje kuphela esimweni somhlabathi, lapho ku-orbit engashintshi (ehlala ihleli), ama-electron awamunci noma akhiphe amandla.
Isitatimende sesi-3 asilungile, esifanele yi-line spectrum, hhayi i-continuous spectrum. I-continuous spectrum iyimodeli ye-athomu kaRutherford.
Isitatimende sesi-4 silungile: ama-electron akhipha amandla ngesimo sama-photon akhanyayo uma ethuthela endaweni ejulile. Uma ethuthela endaweni engaphandle kakhulu, ama-electron amunca amandla ngesimo sama-photon akhanyayo.
Impendulo efanele ngu-D.
6. Lezi zitatimende ezilandelayo zihlobene nemodeli ye-athomu:
(1) Ama-athomu akhiwa yi-nucleus ye-athomu eshajelwe kahle kanye nama-electron ashajelwe kabi azungeza i-nucleus ye-athomu.
(2) Ama-electron azungeza i-nucleus ye-athomu ngaphansi kwethonya lamandla kagesi aqinile.
(3) Ama-electron ajikeleza i-nucleus ngokuqhubekayo azolahlekelwa amandla ukuze i-spectrum ephumayo ibe yi-spectrum eqhubekayo.
(4) Ama-electron azokhipha amandla uma eshintsha imijikelezo.
Isitatimende esingenhla esifakiwe kumbono kaRutherford we-athomu sithi...
A. (1) kuphela
B. (2) kuphela
C. (3) kuphela
D. (1) kanye (2)
E. (2) kanye no-(3)

(1) Lesi sitatimende siyimodeli ye-athomu kaRutherford.
(2) Lesi sitatimende siwukusetshenziswa komthetho kaCoulomb (amandla kagesi)
(3) Lesi sitatimende siyisitatimende semfundiso kaMaxwell ethi ukusheshisa kweshaja kagesi kuzokhipha amagagasi kagesi, ukuze amandla e-electron aphelele ama-electron anciphe.
(4) Lesi sitatimende siyimodeli ye-athomu ye-Bohr.
Impendulo efanele ngu-A.
