why u are talking about heavier elements oxidization state

See here it is talking about oxidising agent means the element itself undergoes self reduction...as down the group the heavier elements oxidation state is more stable...so it resist undergoes self reduction

so cr(VI) become strongest oxidising agent in grp 6

Higher oxidation states of heavier members of group 6 of transition series are more stable. Cr(VI) is strongest oxidising agent in acidic medium

cr2o7 strongest oxidising agent hai in sabhi se...kyunki niche wale jyada stable hai..or jaha tak acidity ki baat hai...more oxidation state more acidic hote hai
