When do the melting points of transition metals rise to a maximum in a row?

Options

  1. AAt the beginning of each series
  2. BAt the end of each series
  3. CAt d5 configuration
  4. DAs the atomic number increases

Correct answer

C. At d5 configuration

Step-by-step solution

In any row, the melting points of these metals rise to a maximum at d5 except for anomalous values of Mn and Tc.
