Which metal in the first series of transition metals exhibits +1 oxidation state most frequently and why?

Options

  1. AIron (Fe) because it has the highest atomic number in the series.
  2. BCopper (Cu) because it readily loses one electron (present in 4s orbital) to give stable 3d 10 electronic conf
  3. CScandium [SC] because it has the lowest ionization energy in the series.
  4. DChromium (Cr) because it readily loses electrons.

Correct answer

B. Copper (Cu) because it readily loses one electron (present in 4s orbital) to give stable 3d 10 electronic conf

Step-by-step solution

Correct Option is : (B) Copper (Cu) because it readily loses one electron (present in 4s orbital) to give stable 3d 10 electronic configuration.
