u cannot write francium i guess u had to write caesium because francium is radioactive so it is never included just like the last element of group 7

 

[urwahboy]

What was the question about oxidation? The one where it was zinc or vanadium? I can't remember what I wrote cuz I can't remember th question!

 

[IGCSE O/L student]

Zn2+ + V4+-----> Zn3+ V3+
i'm not sure.
the question was something like this

 

[WhizAly]

Both were vanadium..
Vandium is redcued so it is oxidant.

because vanadium is the oxidising agent, and so is the oxidant!
