Question

A metal M does not combine with reagents A and B individually but when combines with an appropriate mixture of reagents A and B produce a gas G₁. This gas can also be produced by reaction of other metal of same family and dil. solution of reagent. On the basis of above information which of the following statements is/are true?
(I) These metals may belong to transition metals
(II) Gas G₁ is paramagnetic and blue color gas
(III) Metals of same family which are lighter than M produces same gas reaction with reagent B
