They are generally considerably always more toxic, thanks to much higher redox potential: without oxygen in the form of O2 life would not exist, while all its compounds, where is more than divalent are highly toxic.
Wao ni ujumla zaidi ya sumu daima makubwa, shukrani kwa kiasi Potential Higher Redox: bila oksijeni katika fomu ya O 2 Je, si maisha zipo, wakati wake wote misombo, ambapo ni Zaidi ya divalent ni yenye sumu.
