The value of Kc for this reaction is 4.27.
Balanced chemical reaction: Fe3+(aq) + 3OH–(aq) ⇌ Fe(OH)3
c(Fe3+) = 0.555 M; concentration of iron ions
c(OH-) = 0.750 M; concentration of hydroxide ions
m(Fe(OH)3) = 3.6 g; mass of iron(III) hydroxide
The equilibrium constant (Kc) is a ratio of the concentration of the products to the concentration of the reactants (in this reaction iron and hydroxide ions). Concentration of the product is 1, because it is in the solid state.
Kc = 1 / c(Fe3+) x c(OH-)³
Kc = 1 / (0.555 M x (0.750 M)³
Kc = 4.27; equilibrium constant for this reaction.

Answer:
A positive ion has fewer electrons, and importantly, fewer electron shells (since atoms usually lose electrons until they get down to an empty outer shell.) This makes it smaller than a neutral atom of that element.
A negative ion has more electrons, and importantly, greater electron-electron repulsion in its outer shell. This makes it larger than a neutral atom of that element.
