Zinariya karfe ne mai daraja.Mutane da yawa suna saya shi don manufar adanawa da kuma sanin darajarsa.Amma abin damuwa shi ne yadda wasu ke ganin an yi tsatsa da sandunansu na zinare ko tsabar zinare na tunawa.
Zinariya zalla ba zai yi tsatsa ba
Yawancin karafa suna amsawa da iskar oxygen don samar da karfe oxides, wanda muke kira tsatsa.Amma a matsayin ƙarfe mai daraja, zinari ba ya tsatsa.Me yasa?Wannan tambaya ce mai ban sha'awa.Muna buƙatar warware asirin daga ainihin kaddarorin zinariya.
A cikin ilmin sunadarai, oxidation reaction shine tsarin sinadarai wanda wani abu ya rasa electrons kuma ya zama ions masu kyau.Saboda yawan abun ciki na iskar oxygen a yanayi, yana da sauƙin samun electrons daga wasu abubuwa don samar da oxides.Saboda haka, mun kira wannan tsari hadawan abu da iskar shaka dauki.Ikon iskar oxygen na samun electrons tabbatacce ne, amma yiwuwar kowane sinadari ya rasa electrons ya bambanta, wanda ya danganta da ƙarfin ionization na mafi ƙarancin electrons na element.
Tsarin atomic na zinariya
Zinariya yana da ƙarfin juriya na iskar shaka.A matsayin karfen miƙa mulki, ƙarfin ionization na farko ya kai 890.1kj/mol, na biyu kawai zuwa mercury (1007.1kj/mol) akan damansa.Wannan yana nufin cewa yana da matukar wahala iskar oxygen ta kama na'urar lantarki daga zinari.Zinariya ba wai kawai yana da ƙarfin ionization mafi girma fiye da sauran karafa ba, amma kuma yana da haɓakar atomization mai ƙarfi saboda rashin haɗaɗɗun electrons a cikin kewayar 6S.Atomization enthalpy na zinari shine 368kj / mol (mercury shine kawai 64kj / mol), wanda ke nufin cewa zinari yana da ƙarfi dauri mai ƙarfi, kuma atom ɗin zinare suna sha'awar juna sosai, yayin da atom ɗin mercury ba sa sha'awar juna sosai, don haka yana da sauƙi a haƙa da sauran ƙwayoyin zarra.
