Which properties of element depend on the electronic configuration of atoms and which do not
(b) Why the chemical properties of a group are similar Why do they not have identical properties
(c ) Account for the great chemical similarity of the lanthanoid elements (Z =57 to 71)
(d) Select the largest species in each group
(i) `Ti^(2),Ti^(+3)` (ii) `F^(Θ),Ne,Na^(o+)`
(e) Select the species with the largest `IE` in each group
(i )`na,K,Rb` (ii) F,Ne,Na

(g) Select among the element that has the lowest and highest IE `K, Ca, Se, B, Kr`,
(h) The ionic radii of `S^(2-)` and `Te^(2-)` are and 220 pm respectively Predict the ionic radius of `Se^(2-)` and for `p^(3-)`
(i) In the ionic compound `KF` the `K^(o+)` and `F^(o+)` have practically identical radii, about 134 pm each. Predict the relative atomic radii of 1`K` and `F` .
