which of the m+2 or m+3 ions of the first row of transtional elements are stable in aqueous solutions, which are oxidizing and which are reducing ?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the answer is 1260
