(a) Deduce the number of 3d electrons in the folloing ions :
`Cu^(2+) , Sc^(+3)`

Write down the number of 3d electrons in each of the following ions : Ti^(2+), V^(2+), Cr^(3+), Mn^(2+), Fe^(2+), Co^(2+), Ni^(2+) and Cu^(2+) . Indicate how would you expect the five 3d orbitals to be occupied for these hydrated ions (octahedral).

Write down the number of 3d electrons in each of the following ions : Ti^(2+), V^(2+), Cr^(3+), Mn^(2+), Fe^(2+), Co^(2+), Ni^(2+) and Cu^(2+) . Indicate how would you expect the five 3d orbitals to be occupied for these hydrated ions (octahedral).

Calculate the number of d-electrons in the following ions : Ti^(2+), V^(2+), Cr^(3+), Mn^(2+), Fe^(2+), Fe^(3+), Co^(2+), Ni^(2+), Cu^(2+) .

Write down the number of 3d electrons in each of the following ions: Ti^(2+),V(2+), Cr^(3+),Mn^(2+), Fe^(2+),Fe^(3+),Co^(2+),Ni^(2+) " and " Cu^(2+) . Indicate how would you expect the five 3d orbitals to be occupied for these hydrated ions (octahedral).
