    Exclamation **CHEMISTRY HELP** What is the oxidation number of V in V2O5 ????

    I had a chemistry exam today and they asked for the oxidation number of vanadium, I wrote +5, using the oxidation number of O as being -2, but apparently the oxidation number of O in metals is -1 or -3??? someone pls confirm whether i got it right or wrong

    Oxygen is -2. So for each oxygen it will be -10, two vanadium so yes vanadium is +5!

    Isn't it easier to just count valence electrons?

    how can you find oxidation number by counting valence electrons? you just use charge

    valence electrons vary with transition metals. then u gotta do electron config.
