4. Kusiyana pakati pa chiphunzitso cha atomiki cha Rutherford ndi chiphunzitso cha atomiki cha Bohr ndi...
A. Mu chiphunzitso cha atomiki cha Bohr, sipekitiramu ya atomu ya haidrojeni ndi yosiyana, pomwe mu chiphunzitso cha atomiki cha Rutherford ndi yopitilira.
B. Mu chiphunzitso cha atomiki cha Bohr, ma elekitironi amazungulira nyukiliyasi pamene akupereka mphamvu, pomwe mu chiphunzitso cha atomiki cha Rutherford satulutsa mphamvu.
C. Mu chiphunzitso cha atomiki cha Bohr, ma elekitironi amazungulira mu orbit yosasuntha, pomwe chiphunzitso cha Rutherford chili mu mawonekedwe a parabolic orbit.
D. Mu chiphunzitso cha atomiki cha Bohr, ma orbit osasuntha alibe mphamvu, pomwe mu chiphunzitso cha Rutherford, orbit iliyonse ili ndi mphamvu.
E. Mu chiphunzitso cha atomiki cha Bohr, ma elekitironi sangasinthe ma obiti, pomwe mu chiphunzitso cha Rutherford ma elekitironi amatha kusintha ma obiti.

5. Samalani mawu otsatirawa okhudza chiphunzitso cha atomiki!
(1) Kayendedwe ka ma elekitironi kuzungulira nyukiliyasi nthawi zonse kamakhala kokhazikika.
(2) Ma electron satulutsa mphamvu mu nthaka.
( 3) Kuchuluka kwa mpweya wa maatomu a haidrojeni kumapitirira.
(4) Pamene ma elekitironi asintha njira, ma photoni angapo amatulutsidwa/kuyamwa.
Mawu olondola omwe ali pamwambapa okhudza chitsanzo cha atomiki cha Bohr ndi awa…
A. (1), (2), ndi (3)
B. (1) ndi (3) zokha
C. (1), (3), ndi (4) zokha
D. (2) ndi (4) zokha
E. (2), (3), ndi (4) zokha

Chiganizo 1 ndi chowonadi, njira yozungulira ma elekitironi nthawi zonse imakhala yokhazikika koma ma elekitironi amatha kusuntha kuchokera panjira imodzi (orbit) kupita ku ina.
Chiganizo chachiwiri ndi chowona, osati kokha pamene dziko lapansi lili pansi, pamene ma elekitironi samatenga kapena kutulutsa mphamvu mumlengalenga (nthawi zonse amakhala okhazikika).
Chiganizo chachitatu ndi cholakwika, cholondola ndi mzere wa spectrum, osati spectrum yokhazikika. Mtundu wa spectrum yokhazikika ndi chitsanzo cha atomiki cha Rutherford.
Chiganizo chachinayi ndi cholondola: ma elekitironi amatulutsa mphamvu mu mawonekedwe a ma photoni owala akamapita ku malo ozungulira akuya. Akapita ku malo ozungulira akunja, ma elekitironi amayamwa mphamvu mu mawonekedwe a ma photoni owala.
Yankho lolondola ndi D.
6. Mawu otsatirawa akukhudzana ndi chitsanzo cha atomiki:
(1) Maatomu amapangidwa ndi nucleus ya atomiki yomwe ili ndi mphamvu zabwino komanso ma elekitironi omwe ali ndi mphamvu zoyipa omwe amayendayenda mozungulira nucleus ya atomiki.
(2) Ma electron ozungulira nyukiliyasi ya atomu motsogozedwa ndi mphamvu zamagetsi.
(3) Ma electron omwe amazungulira nyukiliyasi mosalekeza amataya mphamvu kotero kuti sipekitiramu yomwe imachokera imakhala sipekitiramu yopitilira.
(4) Ma electron adzatulutsa mphamvu ngati asintha mayendedwe.
Mawu omwe ali pamwambapa omwe akuphatikizidwa mu chiphunzitso cha atomiki cha Rutherford ndi ...
A. (1) yokha
B. (2) yokha
C. (3) yokha
D. (1) ndi (2)
E. (2) ndi (3)
Zokambirana
(1) Chiganizo ichi ndi chitsanzo cha atomiki cha Rutherford.
(2) Mawu awa ndi kugwiritsa ntchito lamulo la Coulomb (mphamvu yamagetsi)
(3) Mawu awa ndi mawu a chiphunzitso cha Maxwell chomwe chimati kufulumira kwa mphamvu yamagetsi kudzatulutsa mafunde amagetsi, kotero kuti mphamvu yonse ya maelekitironi ya maelekitironi idzachepa.
(4) Chiganizo ichi ndi chitsanzo cha atomiki cha Bohr.
