Kufotokozera kwa Ma Electron ndi Ma Protoni
Pendauluan
Ma electron ndi ma proton ndi mitundu iwiri ya tinthu tating'onoting'ono tomwe ndi tofunikira kwambiri mu fizikisi ndi chemistry. Ndiwo maziko omangira ma atomu, omwe ndi maziko a zinthu zonse m'chilengedwe chonse. Kumvetsetsa ma electron ndi ma proton ndikofunikira kwambiri pophunzira kapangidwe ka ma atomu, machitidwe a mankhwala, ndi zochitika zina zambiri zakuthupi. Nkhaniyi ikambirana za chiyambi, katundu, ndi ntchito za ma electron ndi ma proton.
Ma electron: Tinthu tomwe tanyozedwa molakwika
Mbiri ya Kupeza Zinthu
Ma electron adapezeka koyamba ndi katswiri wa sayansi ya zamoyo J.J. Thomson mu 1897 kudzera mu kuyesa kwa chubu cha cathode ray. Kupeza kumeneku kunasintha momwe timaonera kapangidwe ka zinthu. maatomu ochokera ku chitsanzo Pudding ya plum kukhala chitsanzo chapamwamba kwambiri.
Katundu wa Ma Electron
Ma electron ndi tinthu tating'onoting'ono tomwe tili ndi mphamvu yoipa (-1). Kulemera kwa electron ndi pafupifupi 9.109 × 10^-31 kilogalamu, komwe ndi kochepa kwambiri poyerekeza ndi kuchuluka kwa ma proton ndi ma neutroni. Ngakhale kuti ndi opepuka, ma electron amagwira ntchito yofunika kwambiri pazochitika zosiyanasiyana zakuthupi ndi zamankhwala.
Kugawa kwa Ma Electron mu Atomu
Ma electron amagawidwa m'magawo kapena "zipolopolo" kuzungulira nyukiliyasi (pakati pa atomu). Chipolopolo chilichonse chili ndi mulingo wosiyana wa mphamvu, ndipo ma electron amakonda kukhala mu gawo lomwe lili ndi mphamvu yocheperako yomwe ilipo. Chiphunzitso cha quantum mechanics imapereka dongosolo la masamu lomvetsetsa machitidwe a ma elekitironi mu maatomu, kudzera mu malingaliro a ntchito za mafunde ndi kuthekera.
Udindo wa Ma Electron
Ma electron ndi omwe amachititsa zinthu zambiri pa sikelo ya microscopic ndi macroscopic. Mu chemistry, ma electron omwe ali mu chipolopolo chakunja (ma electron a valence) amachita gawo lofunika kwambiri pa ma chemical bond ndi chemical reactions. Mu magetsi ndi maginito, kuyenda kwa ma electron ndi komwe timakutcha kuti magetsi.
Protoni: Tinthu Tomwe Tili ndi Positively Charged
Mbiri ya Kupeza Zinthu
Ma protoni anapezeka ndi Ernest Rutherford mu 1919 kudzera mu zoyeserera momwe adaphulitsira nayitrogeni ndi tinthu ta alpha, zomwe zinapanga tinthu ta hydrogen tokha. Kupeza kumeneku kunapangitsa kuti anthu amvetse kuti nyukiliyasi ya atomiki imakhala ndi ma protoni ndi ma neutron.
Katundu wa Ma Protoni
Putoni ndi tinthu tating'onoting'ono tomwe tili ndi mphamvu yabwino (+1) komanso kulemera kwa makilogalamu pafupifupi 1.672 × 10^-27, komwe ndi kwakukulu kuposa kulemera kwa elekitironi. Mapulotoni, pamodzi ndi ma neutroni, amapanga nyukiliyasi ya atomu, yomwe imapanga gawo lalikulu la kulemera kwa atomu.
Malo a Ma Protoni mu Atomu
Mapulotoni ali mu nyukiliyasi, yomwe ndi pakati pa atomu, yomwe ndi yaying'ono poyerekeza ndi kukula kwa atomu yonse. Chinthu chilichonse cha mankhwala chimatanthauzidwa ndi kuchuluka kwa mapulotoni mu nyukiliyasi yake, komwe kumadziwika kuti nambala yake ya atomu. Mwachitsanzo, kaboni ili ndi mapulotoni asanu ndi limodzi mu nyukiliyasi yake, pomwe mpweya uli ndi asanu ndi atatu.
Udindo wa Ma Protoni
Mapulotoni amapereka bata ndi kudziwika kwa maatomu. Mapulotoni amachitanso gawo pa mgwirizano wamphamvu wa nyukiliya, mphamvu yofunikira yomwe imagwirizira nyukiliya pamodzi mwa kumangirira mapulotoni ndi ma neutron pamodzi. Kuphatikiza apo, mu zochita za mankhwala, kusintha kwa chiwerengero cha mapulotoni kumatha kusintha chinthu chimodzi kukhala china kudzera mu zochita za nyukiliya.
Kuyanjana ndi Ubale Pakati pa Ma Electron ndi Ma Protoni
Mphamvu ya Magetsi
Ma electron ndi ma proton amalumikizana wina ndi mnzake kukopeka wina ndi mnzake chifukwa cha kalembedwe Magetsi. Mphamvu yokoka iyi ndiyo maziko a kapangidwe ka atomu. Ma electron omwe amazungulira nyukiliyasi amakhala ndi mtunda winawake chifukwa cha kulinganiza pakati pa mphamvu yokoka ma protoni ndi mphamvu ya kinetic ya ma electron.
Maatomu ndi Mphamvu yamagetsi
Mu mkhalidwe wopanda tsankho, atomu imakhala ndi chiwerengero chofanana cha ma protoni ndi ma elekitironi, kotero mphamvu yake yonse ndi zero. Komabe, ma atomu amatha kutaya kapena kupeza ma elekitironi, kukhala ma ayoni omwe ali ndi mphamvu zabwino (cations) ngati ataya ma elekitironi, kapena ma ayoni omwe ali ndi mphamvu zoyipa (anions) ngati ataya ma elekitironi. Njirayi ndi yofunika kwambiri pazochitika zambiri zamakemikolo ndi ntchito zosiyanasiyana zaukadaulo, kuphatikizapo mabatire ndi maselo a electrolytic.
Mabond a Mankhwala
Ma chemical bonds amachitika chifukwa cha kuyanjana pakati pa ma electron m'zipolopolo zakunja za ma atomu. Ma proton, kudzera mu ma electron awo, amatsimikiza momwe ma atomu adzachitirana. Pali mitundu ingapo ya ma chemical bonds, kuphatikizapo ma covalent, ionic, ndi metallic bonds, onse omwe amakhudza ma electron mwanjira ina.
Mapulogalamu ndi Zotsatira zake
Mu Ukadaulo Wamakono
Ma electron amagwira ntchito yofunika kwambiri pafupifupi muukadaulo wamakono wamagetsi. Kuyambira ma semiconductor mkati mwa makompyuta ndi mafoni am'manja mpaka zida zamankhwala ndi ukadaulo wazidziwitso, machitidwe a ma electron muzinthu ndi ma circuits ndi ofunikira kwambiri pakugwira ntchito kwawo.
Fiziki ya Nyukiliya ndi Ma Nuclear Reactors
Mapulotoni ndi ofunikira kwambiri pa sayansi ya nyukiliya ndi ukadaulo wa nyukiliya. Mu kusakanikirana kwa nyukiliya, mapulotoni amaphatikizana kupanga helium, kutulutsa mphamvu panthawiyi. Iyi ndiye mfundo yaikulu ya dzuwa ndi nyenyezi zonse, komanso ndi gawo lofufuza. magwero a mphamvu zatsopano, zoyera, komanso zogwira mtima kwambiri.
Zotsatira zake mu Biology
Mu biology, mapulotoni amagwira ntchito yofunika kwambiri mu njira zosiyanasiyana za biochemical. Mwachitsanzo, kuchuluka kwa pulotoni kudutsa nembanemba ya selo kumagwiritsidwa ntchito popanga adenosine triphosphate (ATP), molekyulu yomwe imapereka mphamvu pafupifupi machitidwe onse a maselo m'zamoyo.
Kutseka
Ma electron ndi ma proton ndi tinthu tating'onoting'ono tomwe timapanga zinthu m'chilengedwe chonse. Ndi makhalidwe osiyana koma ogwirizana, zimathandiza zochitika zovuta zakuthupi ndi zamakemikolo, kuyambira kapangidwe ka atomu mpaka kusintha kwa mankhwala ndi ukadaulo wamakono. Kumvetsetsa mozama tinthu timeneti sikuti kumangowonjezera chidziwitso chathu cha chilengedwe chonse komanso kumatsegula chitseko cha zatsopano zaukadaulo zomwe zimakhudza mbali zambiri za miyoyo yathu.
