The first ionisation energies of the elements of the first transition

1.	The first ionisation energies of the elements of the first transition series `(TitoCu)`A. increases as the atomic number increasesB. decreases as the atomic number invreasesC. do not show any change as the addition of electrons takes place in the inner (n- 1) d orbitalsD. increases from Ti to Mn and then decreases from Mn to Cu.
Answer» Correct Answer - A First ionisation energy of the elements of first transition series `(Ti to Cu)` increases as the atomic number increases due to increases of nuclear charge. The increase however is not regular.
