Question

The first ionization energies of the elements of the first transition series (Ti to Cu)

A

Increase as the atomic number increases

B

Decrease as the atomic number increase

C

Do not show any change as the addition of electrons takes placed in the inner (n-1) d-orbitals

D

Increase from Ti to Mn and then decrease from Mn to Cu.

Answer

Increase as the atomic number increases

Explanation

Solution

First ionization energy of the elements of first transition series $(Ti \rightarrow Cu)$ increase as the atomic number increases due to increase of nuclear charge. The increase however is not regular.
