Question

Fe3+ ion is more stable than Fe2+ ion because

a) more than charge on the atom, more is its stability

b) configuration of Fe2+ is 3d5

while Fe3+ is 3d5

c) Fe2+ has a larger size than Fe3+

d) Fe3+ ions are coloured hence more stable​

Answer 1

Answer:

Fe³+ ion is more stable than Fe²+ ion because:

Fe³+ has 3d⁵ half filled configuration whereas Fe²+ has 3d⁶ configuration.
