Ndeupi Musiyano Pakati peZinc neMagnesium?

Musiyano wakakosha pakati pezinc uye magnesium ndewekuti zinc isimbi yekumashure, nepo magnesium iri alkaline pasi simbi.
Zinc uye magnesium zvinhu zvemakemikari zveperiodic tafura.Zvinhu zvemakemikari izvi zvinonyanya kuitika sesimbi.Nekudaro, ivo vane akasiyana makemikari uye emuviri zvimiro nekuda kweakasiyana maelektroni masisitimu.

Chii chinonzi Zinc?

Zinc chinhu chemakemikari chine nhamba yeatomu 30 uye chiratidzo chemakemikari Zn.Ichi chemikemikari chinhu chakafanana nemagnesium kana tichifunga nezvemakemikari ayo.Izvi zvinonyanya nekuti zvese izvi zvinhu zvinoratidza +2 oxidation state seyakagadzika oxidation mamiriro, uye Mg + 2 uye Zn + 2 cations ane saizi yakafanana.Uyezve, ichi ndicho chikamu chechi24 chemakemikari akawandisa pasi penyika.

Huremu hweatomiki hwezingi 65.38, uye inoratidzika sesirivha-grey yakasimba.Iri muboka 12 uye nguva 4 yeperiodic table.Ichi chemakemikari chinhu ndeche d block yezvinhu, uye inouya pasi peiyo post-transition simbi chikamu.Uyezve, zinc yakasimba pane yakajairwa tembiricha uye kudzvanywa.Iine crystal structure hexagonal close-packed structure.

Zinc simbi idiamagnetic simbi uye ine bluish-chena inopenya inopenya.Pakupisa kwakawanda, simbi iyi yakaoma uye ine brittle.Zvisinei, inova inoumbika, pakati pe100 ne150 °C.Uyezve, iyi ndiyo yakanaka conductor yemagetsi.Nekudaro, ine yakaderera kunyungudika uye kubikira mapoinzi kana ichienzaniswa nemamwe akawanda masimbi.

Kana tichitarisa kuitika kwesimbi iyi, goko repasi rine 0.0075% ye zinc.Tinogona kuwana chinhu ichi muvhu, mvura yegungwa, mhangura, uye lead ores, etc. Mukuwedzera, chinhu ichi chinonyanya kuwanikwa pamwe chete nesarufa.

Chii chinonzi Magnesium?

Magnesium chinhu chemakemikari chine nhamba yeatomu 12 uye chiratidzo chemakemikari Mg.Kemikari iyi inoitika segrey-inopenya yakasimba patembiricha yemumba.Iri muboka 2, nguva 3, muperiodic table.Naizvozvo, tinogona kuitumidza sechinhu che s-block.Uyezve, magnesium ndeye alkaline pasi simbi (boka rechipiri chemakemikari zvinhu zvinonzi alkaline pasi simbi).Iyo electron configuration yesimbi iyi [Ne] 3s2.

Magnesium simbi ikemikari yakawanda iri muchadenga.Sezvingatarisirwa, simbi iyi inoitika pamwe chete nemamwe makemikari zvinhu.Kunze kwezvo, iyo oxidation mamiriro e magnesium ndeye +2.Iyo yemahara simbi inoshanda zvakanyanya, asi isu tinogona kuigadzira sechinhu chekugadzira.Inogona kupisa, ichibudisa chiedza chakajeka zvikuru.Tinoti chiedza chichena chinopenya.Tinogona kuwana magnesium ne electrolysis ye magnesium munyu.Iyi magnesium munyu inogona kuwanikwa kubva kune brine.

Magnesium isimbi isina huremu, uye ine hutsika hwakadzikira hwekunyunguduka nekuvirisa pakati pesimbi dzepasi.Iyi simbi zvakare ine brittle uye nyore inoputsika pamwe chete nemabhendi ekugera.Kana yakasanganiswa nealuminium, iyo alloy inova yakanyanya ductile.

Kuita pakati pe magnesium nemvura hakusi kukurumidza se calcium uye mamwe alkaline pasi simbi.Patinonyudza chidimbu che magnesium mumvura, tinogona kuona mabhuru ehydrogen achibuda kubva pamusoro pesimbi.Zvisinei, mhinduro yacho inomhanya nemvura inopisa.Uyezve, simbi iyi inogona kuita nemaasidhi exothermally, semuenzaniso, hydrochloric acid (HCl).

Ndeupi Musiyano Pakati peZinc neMagnesium?

Zinc uye magnesium zvinhu zvemakemikari zveperiodic tafura.Zinc ikemikari ine nhamba yeatomu 30 uye kemikari chiratidzo Zn, nepo magnesium iri kemikari ine nhamba yeatomu 12 uye kemikari chiratidzo Mg.Musiyano wakakosha pakati pezinc uye magnesium ndewekuti zinc isimbi yekumashure, nepo magnesium iri alkaline pasi simbi.Uyezve, zinc inoshandiswa mukugadzira alloys, galvanizing, mota zvikamu, magetsi emagetsi, nezvimwewo, nepo magnesium ichishandiswa sechikamu chealuminium alloys.Izvi zvinosanganisira alloys anoshandiswa mumagaba echinwiwa ealuminium.Magnesium, yakasanganiswa zinc, inoshandiswa mukukanda kufa.
