Izakhi zamakhemikhali zakha i-DNA yendawo yonke. Ukusuka kumoya-mpilo esiwuphefumulayo kuye ku-silicon kumadivayisi ethu, zonke zimelelwe ku- ithebula lesikhathi. Nokho, ithebula le-periodic lingabonakala njengemephu engachazeki yezimpawu nezinombolo kwabaningi bethu.
Singayenza kanjani le atlasi yezinto ukuthi ifinyeleleke kalula? Ngenxa yobuchwepheshe, kunezinhlelo zokusebenza ezimangalisayo laphaya, futhi nakuba kungezona zonke ezimahhala, zizokusiza ukuthi ufunde futhi uqonde ithebula le-periodic kalula. Masizithole ndawonye.
Liyini ithebula le-periodic?
Ake siqale ekuqaleni. Ithebula le-periodic lezinto liwuhlelo oluhlelekile lwezakhi zamakhemikhali, ezihlelwe ngokwezakhiwo zazo nokuziphatha kwamakhemikhali. Yasungulwa ngu Dmitri Mendeleyev ngo-1869, owasekela umklamo wakhe ebudlelwaneni phakathi kwenqwaba ye-athomu yezakhi kanye nezakhiwo zazo zamakhemikhali. Nokho, enguqulweni yesimanje yethebula, izakhi zihlelwa ngokusekelwe enombolweni yazo ye-athomu (okungukuthi, inani lamaphrothoni kuyinucleus ye-athomu) kunesisindo sazo se-athomu.
Ithebula le-periodic lihlukaniswe ngemigqa namakholomu., lapho umugqa ngamunye umele khona isikhathi futhi ikholomu ngayinye imelela iqembu. Kunezikhathi eziyi-7 sezizonke, ezivundlile, namaqembu ayi-18, aqondile. Amaqembu abaluleke kakhulu ngoba izakhi zeqembu elifanayo zivame ukwabelana ngezakhi zamakhemikhali ezifanayo ngoba zinenani elifanayo lama-electron ezingeni lawo lamandla angaphandle.
Iphinde ihlukaniswe ngamabhlogo. I-s block ihlanganisa amaqembu amabili ngakwesobunxele (i-alkali nomhlaba we-alkali), i-p block ihlanganisa amaqembu ayisithupha kwesokudla (i-boron kuya kumaqembu e-helium), i-d block ihlanganisa amaqembu ayishumi enguquko enkabeni yetafula. , kanye ne-block f ihlanganisa ama-lanthanides nama-actinides, okuthi ngenxa yezizathu zesikhala ngokuvamile abekwe ngokwehlukana, ngaphansi komzimba omkhulu wetafula.
Ngaphezu kokunikeza indlela esheshayo nelula yokuhlonza izakhiwo zamakhemikhali zezakhi, ithebula le-periodic futhi wenza izibikezelo mayelana nezakhi ezingakatholwa. Kafushane, iyithuluzi eliyisisekelo kukhemistri nezinye isayensi, elisiza ukuqonda ubudlelwano, izitayela kanye nezakhiwo zezakhi, kube ithuluzi elibalulekile lanoma yimuphi umfundi wamakhemikhali noma wekhemistri.
Ukufunda ithebula le-periodic kungaba umsebenzi oyinselele ngenxa yolwazi oluqukethe. Kodwa-ke, ngenxa yezinhlelo zokusebenza ezahlukahlukene esizibalulile ngenhla, ukufunda ithebula le-periodic kungaba ukuzizwisa okusebenzisanayo, okubukwayo nokuzijabulisa.
Ngakho-ke ungangabazi ukuzama noma iyiphi yazo futhi uthole umhlaba omangalisayo wezakhi zamakhemikhali!
Izinhlelo zokusebenza ezingcono kakhulu zokufunda ithebula le-periodic
Kusuka Soy de Mac Sihlaziye izinhlelo zokusebenza ezimbalwa ukuze sikwazi ukufunda i-Periodic Table of the Elements futhi kulokhu sikulethela lezo esikholelwa ukuthi ziwusizo kakhulu ekufundeni kwakho.
- Ithebula le-Periodic Elements
Uhlelo lokusebenza Ithebula le-Periodic Elements iwumtapo wezincwadi onemininingwane wethebula le-periodic. Into ngayinye ichazwa ngokujulile ngemininingwane ngomlando wayo, ukutholwa, izakhiwo, kanye nokusetshenziswa kwayo.
Okuyenza ihluke kwezinye izinhlelo zokusebenza isethulo solwazi esikhangayo, esihambisana nezithombe nezithombe ezisezingeni eliphezulu. Izitshudeni zingahlanganyela nama-elementi ekumeleleni okunezinhlangothi ezintathu okunikeza ukuzizwisa okugxilile. Ngaphezu kwalokho, inemidlalo esebenzisanayo eyenza ukufunda kube inqubo yokuzijabulisa.
Ngaphandle kokungabaza, lolu hlelo lokusebenza liyithuluzi lokufunda elibalulekile labafundi be-chemistry kanye nabashisekeli.
- i-atomidoodle
i-atomidoodle ihlanganisa ubumnandi bomdlalo kanye nemfundo yethebula le-periodic. Abadlali kumele baqondise ama-athomu ku-maze, bawahlanganise ndawonye ukuze akhe izakhi. Njengoba abadlali bathuthukela kumaleveli, izinto eziningi ziyaziswa futhi ubunzima buyanda, okusiza abadlali ukuthi bajwayelane nethebula lezikhathi ngendlela yokudlala nenselele. Ngokungafani nezinhlelo zokusebenza zemibuzo evamile, i-Atomidoodle igxile ekunikezeni ulwazi lokufunda olusebenzisanayo olungagcina abasebenzisi bahlanganyele isikhathi eside.
- The Elements nguTheodore Gray
The Elements nguTheodore Gray igqama ngemifanekiso yayo emangalisayo nokuqukethwe okucebile. Into ngayinye yethulwa ngento yomhlaba wangempela equkethe into, enikeza abasebenzisi ukuqonda okuphathekayo kokuthi izinto zisetshenziswa kanjani ekuphileni kwansuku zonke.
Abasebenzisi bangazungezisa izinto nge-3D futhi bafunde izincazelo ezinemininingwane mayelana nento ngayinye. Lolu hlelo lokusebenza luthatha ukufunda ithebula lezikhathi kuya ezingeni elisha nelihehayo.
- I-Quizlet
Noma kunjalo I-Quizlet Akulona uhlelo lokusebenza olunikezelwe kuphela etafuleni le-periodic, linamakhadi amaningi adalwe ngabasebenzisi kuthebula le-periodic azokuvumela ukuthi ufunde ngejubane lakho.
Inzuzo ye-Quizlet ukuthi ungakwazi ukwenza ngokwezifiso amakhadi akho okubhala futhi ugxile ezindaweni okudingeka uziqinise. Ngaphezu kwalokho, idizayini yayo yomdlalo yenza ucwaningo luhlanganyele futhi lube mnandi.
- I-ChemTable
I-ChemTable inikeza abafundi indlela elula kodwa esebenzayo yokufunda ithebula le-periodic. I-elementi ngayinye inemininingwane ngezakhiwo zayo, njengenombolo ye-athomu, inqwaba ye-athomu, nokucushwa kwe-electronic, phakathi kokunye.
