The microorganisms can change the chemicalvalence of the vanadium, thereby changing its toxicity.
表明微生物能改变钒的价态。从而改变其毒性。

Only strictly controlling the temperature can it be prepared what needed especially for the Cobalt, Manganese precursors because of many chemicalvalence.
只有控制严格的温度才能制备出所需的产物，尤其对于化合价较多的钴、锰前驱物要尤为重视。

Now with this framework, I said that talking about these valence electrons might give us some insight into chemical reactivity.
