Manganese, uas yog nyob rau nruab nrab ntawm lub sijhawm, muaj cov oxidation ntau tshaj plaws, thiab qhov tseeb yog lub xeev oxidation siab tshaj plaws nyob rau hauv tag nrho lub sijhawm vim nws muaj tsib yam tsis muaj hluav taws xob(saib cov lus hauv qab no).
Vim li cas manganese thiaj li muaj oxidation siab tshaj plaws?
(i) Mn qhia txog lub xeev oxidation siab tshaj plaws ntawm + 7 nrog oxygen vim nws tuaj yeem tsim p-pi-d-pi ntau daim ntawv cog lus siv 2p orbital ntawm oxygen thiab 3d orbital ntawm Mn. Ntawm qhov tod tes, Mn qhia txog lub xeev oxidation siab tshaj plaws ntawm +4 nrog fluorine vim nws tuaj yeem tsim ib daim ntawv cog lus nkaus xwb.
Vim li cas Mn Qhia 7 lub xeev oxidation?
Thaum muaj cov pa oxygen, Mn qhia qhov siab tshaj plaws oxidation lub xeev ntawm +7. Qhov no yog vim Mn cov ntaub ntawv pπ–dπ ntau daim ntawv cog lus siv 2p orbitals ntawm oxygen thiab 3d orbitals ntawm Mn Nrog F, Mn qhia txog oxidation xeev ntawm +4 vim yog ib daim ntawv cog lus tsim los ntawm tsis muaj 2p orbitals hauv F rau ntau qhov sib txuas.
Dab tsi yog lub xeev oxidation siab tshaj plaws ntawm manganese?
Cov xeev oxidation feem ntau ntawm manganese yog 2+, 3+, 4+, 6+, thiab 7+. Lub xeev oxidation ruaj khov tshaj plaws rau manganese yog 2+, uas muaj xim liab liab.
Qhov twg yuav muaj lub xeev oxidation siab tshaj?
Lub xeev oxidation siab tshaj plaws yog + 8hauv tetroxides ntawm ruthenium, xenon, osmium, iridium, hassium, thiab qee qhov kev cuam tshuam nrog plutonium; Qhov qis tshaj plaws paub oxidation xeev yog −4 rau qee cov ntsiab lus hauv pawg carbon. Oxidation xeev ntawm plutoniumNtawm no, plutonium txawv ntawm cov xim nrog oxidation xeev.

Vim li cas kuv thiaj muaj siab siab thiab qis qis?
Yuav ua li cas kev puas siab puas ntsws bipolar ? Kev puas siab puas ntsws bipolar yog ib qho kev puas siab puas ntsws uas cim los ntawm kev hloov pauv ntawm lub siab los ntawm siab mus rau qis, thiab los ntawm qis mus rau siab. Highs yog lub sij hawm ntawm mania, thaum lows yog lub sij hawm ntawm kev nyuaj siab.
