What is the factor that causes ionization enthalpy to be unusually high for Cr and Cu?

Options

  1. APresence of more s electrons
  2. BPresence of more d electrons
  3. CPresence of more p electrons
  4. DPresence of more f electrons

Correct answer

B. Presence of more d electrons

Step-by-step solution

The ionization enthalpy is unusually high for Cr and Cu due to the presence of more d electrons.
