5 Ithiyori ye-Atomic kaRutherford Thomson Bohr - izinkinga nezixazululo
1. Ubuthakathaka bombono kaRutherford we-athomu bungu…
A. Ama-electron azungeze i-nucleus ye-athomu azomunca amandla
B. Ama-electron asakazeka ngokulinganayo ebusweni be-athomu eyindilinga
C. Ama-electron ajikeleza umgogodla njengohlelo lwelanga
D. Ama-electron azungeze i-nucleus ekhipha amaza kagesi
E. I-athomu iqukethe amacala amahle nangalungile
Isixazululo
Impendulo efanele ithi C.
2. Isitatimende esisodwa mayelana nemodeli ye-athomu ye-Thomson sithi …
A. Ama-electron angamunca amandla
B. Ama-electron ayahlangana ukuze akhe i-nucleus ye-athomu
C. I-athomu yingxenye encane kunazo zonke
D. Ama-athomu aneshaja engu-(+) kanye no-(-) esatshalaliswa ngokulinganayo
E. Ama-electron aseduze ne-nucleus ye-athomu
Isixazululo
Impendulo efanele ngu-D.
3. Yiziphi kulezi zitatimende ezilandelayo eziwubuthakathaka benkolelo-mbono kaBohr ye-athomu?
A. Angikwazi ukuchaza umphumela we-Zeeman
B. Angikwazi ukuchaza amandla aphakathi kwama-electron
C. Ngokuphambene nemithetho yefiziksi yakudala
D. Ngokuphambene nombono kaDalton
E. Ayikwazi ukunquma amandla okuguquka
Isixazululo
Impendulo eyiyo ngu-A.
4. Umehluko wemibono mayelana nemodeli ye-athomu ngokusho kukaRutherford noBohr uthi …

| A |
I-athomu yakhiwe yi-nucleus eshajelwe kahle kanye ne-electron eshajelwe kabi ehambahamba kuyo yonke i-nucleus |
Ama-electron ahambahamba ezungeze i-nucleus kanti isisindo se-athomu sigxile enkabeni yayoe |
| B |
Ama-electron azungeze i-nucleus ngenkathi ekhulula amandla |
Ama-electron azungeze i-nucleus ku- indlela ethile |
| C |
Ama-electron asendaweni yawo emile indlela amunce amandla |
Ama-electron angakwazi ushiye indlela ngokumunca/ukukhulula amandla |
| D |
Ama-electron ayingxenye ye-athomu eshajelwe ngogesi engemihle |
Ama-electron asatshalaliswa ku-nucleus ye-athomu |
| E |
Isisindo se-athomu sigxile endaweni encane indawo okubizwa ngokuthi i-nucleus |
Ubunzima bama-athomu buyafana kuzo zonke izindawo ku-athomu |
Isixazululo
Impendulo efanele ngu-B.
5. Isitatimende sangempela semodeli ye-athomu kaRutherford kanye nemodeli ye-athomu kaBohr sithi …
|
Rutherford |
Bohr |
|
| A |
Zonke izindleko ezinhle kanye nesisindo esithile se-athomu zikhona ku-nucleus ye-athomu |
Ama-electron awakwazi ukuhambahamba eduze kwe-nucleus ngokusebenzisa indlela ngayinye |
| B |
Ishaja kagesi enhle incishiswa ama-electron ahlakazekile phakathi kwamacala |
Ama-electron ama-athomu ahlala endleleni ye-orbital ebizwa ngokuthi izinga lamandla |
| C |
I-athomu ayithathi hlangothi |
Amandla ama-electron ku-athomu avezwa yizinga lamandla |
| D |
Ama-nuclei akhangayo kanye nama-nuclei e-electron adala amandla aphakathi kwama-electron aholela ekutheni ama-electron ahlale emizuliswaneni yawo |
Ama-electron angahamba esuka komunye umjikelezo (indlela) aye komunye ngokukhulula amandla noma ngokumunca amandla |
| E |
I-nucleus izungezwe ama-electron ajikeleza endleleni efana neplanethi |
Kokunye ukusabela, ama-electron angaphandle kuphela angashintsha ngenkathi i-nucleus ingashintshi. |
Isixazululo
Impendulo efanele ngu-D.
