Tichifunga ndima iyi pamusoro pemagnesium, nhamba yeatomu yemagnesium chii?
Context:Magnesium chinhu chemakemikari chine chiratidzo Mg uye nhamba yeatomu 12. Iyo simbi inopenya grey ine density yakaderera, yakaderera yekunyungudika poindi uye yakakwira kemikari reactivity. Kufanana nedzimwe simbi dzepasi dzine alkaline (boka 2 re periodic table) inowanikwa zvakasikwa chete mukubatana nezvimwe zvinhu uye inenge nguva dzose ine oxidation state ye +2. Inopindirana nyore nyore nemhepo kuti igadzire passivation yakatetepa ye magnesium oxide iyo inodzivisa kuwedzera ngura kwesimbi. Simbi yakasununguka inopisa nechiedza chakajeka chena. Simbi yacho inowanwa zvikurukuru ne electrolysis yemagnesium salts anowanwa kubva mu brine. Iine density yakaderera pane aruminiyamu uye inoshandiswa zvikurukuru sechikamu chezvigadziro zvakasimba uye zvisinganzwisisiki zvine aluminium.
Nhamba yeatomu ye magnesium i12.
