Bayani Game da Electrons da Protons
Fahimtar muhimman abubuwan gina jiki na abu muhimmin ginshiki ne na kimiyyar zamani. A zuciyar ka'idar atomic akwai electrons da protons, abubuwan da ke tsara halaye da halayen atoms. Wannan labarin ya yi nazari kan yanayi, halaye, da mahimmancin electrons da protons, yana bayyana rawar da ke takawa a fagen ƙwayoyin subatomic.
Gano Electrons da Protons
Wutar lantarki
Masanin kimiyyar lissafi na Burtaniya JJ Thomson ne ya fara gano electrons a shekarar 1897. Gwaje-gwajen Thomson da haskokin cathode sun bayyana wanzuwar ƙwayoyin da ke da ƙarancin ƙwayoyin cuta masu caji. Binciken da ya yi ya nuna canjin yanayin fahimtar tsarin atomic, wanda ya haifar da ci gaban samfurin electrons inda electrons ke kewaya tsakiya, suna kama da duniyoyi a kusa da tauraro.
protons
A halin yanzu, Ernest Rutherford ya gano Protons daga baya a shekarar 1917 ta hanyar aikinsa kan ƙwayoyin alpha. Ganin yadda waɗannan ƙwayoyin ke aiki lokacin da suka kai wani hari, Rutherford ya kammala da cewa dole ne ƙwayoyin atom su kasance suna da core mai yawa, mai caji mai kyau. An gano cewa wannan core ya ƙunshi protons, kowannensu yana ɗauke da caji mai kyau wanda ke daidaita cajin electrons mara kyau.
Muhimman Halayen Electrons
Electrons su ne ƙwayoyin halitta masu ƙananan atom waɗanda nauyinsu ya kai kimanin kilogiram 9.109 x 10^-31, wanda yake kusan 1/1836 nauyin proton. Suna ɗauke da cajin negative na 1.602 x 10^-19 coulombs. Ana samun Electrons a yankuna da ke kewaye da tsakiya da aka sani da gajimare na electron ko orbitals, inda suke wanzuwa a matakan makamashi bisa ga ƙa'idodin makanikan quantum.
Tsarin Electron da Injinan Kwatancen
Masana kimiyyar lissafi sun kawo sauyi ga fahimtar halayen electrons, inda suka gabatar da manufar yawan yiwuwar amfani maimakon ma'aunin da aka tsara. Elektrons suna mamaye matakan makamashi daban-daban ko harsashi, waɗanda aka sanya musu suna K, L, M, da sauransu, tare da ƙaruwar nisa daga tsakiya. Tsarin electrons a cikin waɗannan harsashi da ƙananan harsashi (s, p, d, f) yana ƙayyade halayen sinadarai na atom.
Electrons suna nuna halayen barbashi da kuma irin raƙuman ruwa, kamar yadda aka bayyana ta hanyar hasashen de Broglie kuma an tabbatar da hakan ta hanyar abubuwan da suka faru kamar diffraction na electron. Wannan yanayi mai kama da juna yana da mahimmanci ga halayen electrons a cikin ƙwayoyin halitta da ƙwayoyin halitta, wanda ke haifar da samuwar haɗin sinadarai, sha da fitar da haske, da sauran hulɗar sikelin atomic.
Muhimman Halayen Protons
Protons su ne ƙwayoyin halitta masu ƙananan ƙwayoyin halitta da ake samu a cikin ƙwayar zarra, tare da nauyin kimanin kilogiram 1.673 x 10^-27, kusan sau 1836 na nauyin electron. Kowane proton yana ɗauke da caji mai kyau na coulombs 1.602 x 10^-19, wanda ke daidaita cajin electron amma tare da polarity akasin haka.
Adadin protons a cikin wani nucleus, wanda aka sani da lambar atomic (Z), yana bayyana sinadarin. Misali, hydrogen yana da proton guda ɗaya, wanda ya sa lambar atomic ɗinsa ta zama 1, yayin da carbon ke da protons guda shida, wanda ya yi daidai da lambar atomic ta 6. Wannan lambar atomic tana nuna asalin sinadarin da matsayinsa a kan teburin periodic.
Ƙarfin Ƙarfin Makamin Nukiliya
Ana ɗaure protons tare a cikin tsakiya ta hanyar ƙarfin nukiliya mai ƙarfi, ɗaya daga cikin manyan ƙarfi guda huɗu a yanayi. Duk da ƙarfinsu mai kyau, wanda ke haifar da tursasawa ta lantarki a tsakaninsu, ƙarfin nukiliya mai ƙarfi yana da ƙarfi sosai don riƙe protons tare da neutrons, suna samar da ƙwayoyin halitta masu ƙarfi. Wannan ƙarfin yana aiki a ɗan gajeren zango, wanda yayi daidai da girman ƙwayoyin atom.
Hulɗar Electrons da Protons
Kwanciyar Hankali ta Atom
Kwanciyar kwayar zarra wata siffa ce mai sauƙi tsakanin ƙarfin jan hankali da protons ke yi da kuma mu'amalar da electrons ke yi da juna. Nucleus ɗin, wanda ke ɗauke da protons (kuma galibi neutrons), yana jan hankalin electrons da ke kewaye, yana riƙe su a cikin kewayarsu. Wannan jan hankalin electrostatic yana da mahimmanci ga daidaiton kwayar zarra gaba ɗaya.
Idan atom yana da daidai adadin protons da electrons, yana tsaka-tsaki a wutar lantarki. Duk da haka, idan aka samu ko aka rasa electrons, atom ɗin zai zama ion. Ion masu caji mai kyau (cations) suna samuwa lokacin da atom ya rasa electrons, yayin da ions masu caji mara kyau (anions) suna faruwa lokacin da atom ya sami electrons. Waɗannan ions suna taka muhimmiyar rawa a cikin halayen sinadarai da samuwar mahadi.
Sinadarin bonding
Hulɗar da ke tsakanin electrons da protons tana da mahimmanci ga haɗin sinadarai. A cikin haɗin covalent, atoms suna raba nau'i-nau'i na electrons don cimma daidaitattun tsarin electrons, yawanci suna kama da iskar gas mai daraja. Misali, a cikin kwayar ruwa (H2O), oxygen yana raba electrons tare da atom hydrogen guda biyu.
A cikin haɗin ionic, ƙwayoyin halitta suna canja wurin electrons zuwa juna, wanda ke haifar da samuwar ions tare da caji daban-daban, waɗanda ke jawo hankalin juna ta hanyar lantarki. Misalin wannan shine sodium chloride (NaCl), inda sodium ya rasa electron ya zama Na+ ion, kuma chlorine ya sami electron ya zama Cl- ion, wanda ke haifar da ƙirƙirar layin ionic mai ƙarfi.
Muhimmancin Electrons da Protons
