Explain the following observations:
(i) Generally there is an increase in density of elements from titanium (Z = 22) to copper (z =29) in the first series of transition elements.
(ii) Transition elements and their compounds are generally found to be good catalysts in chemical reactions.

(i) How would you account for the following: (a) The transition elements exhibit high enthalpies of atomization. (b) The 4d and 5d series of the transition metals have more
The uncertainty in momentum of an electron is 1 x10 -5 kg- m/s . The uncertainty in its position will be (h= 6.62 x 10 -34 kg - m 2 / s): (1) 1.05 x 10- 28 m
