The ion with the larger radius: Mn2+ or Mn3+ . Explain why.
Radius : Mn2+ > Mn3+
In Mn2+ , no.of protons are more than no.of electrons by two units. Whereas in Mn3+ , no.of protons are more than no.of electrons by three units.Therefore, they can attract the electrons with greater force than in case of Mn2+.
Which species will reduce Mn3+ to Mn2+ (Ecell = 1.51 V) but will NOT reduce Cr3+ to Cr2+ (Ecell = -0.40 V)? (Can you explain with steps on how to find the correct answer, and why the other answers are not correct?)

Explain why compound containing carbonate ion, phosphate ion, chromate ion, and sulfide ion water insoluble? Why compounds containing Li^+, Na^+. K^+, Cs^+, or NH4^+ are exceptions (water soluble)?
Write the condensed ground-state electron configuration of the transition metal ion Mn2+.
answer a b or c Why is the atomic radius of magnesium ion much smaller than that of a neutral charged magnesium atom? (See the atomic radius graph) The magnesium ion's electrons require less space. No electrons are lost, they move to unoccupied spaces about the nucleus. The magnesium ion has fewer principle quantum energy levels, this causes a decrease in atomic radius. The magnesium ion has a higher Z-effective nuclear charge. The magnesium ion has more principle quantum energy...
