The highest oxidation state in plutonium (At. No. = 94) is

Options

  1. A+6
  2. B+4
  3. C+5
  4. D+7

Correct answer

D. +7

Step-by-step solution

The highest oxidation state in plutonium (Atomic number = 94) is + 7. It can show a greater range of oxidation states which (in part) is attributed to the fact 5f, 6d and 7s levels are of comparable energies. Plutonium (Pu) can show oxidation state of +3, +4, +5, +6 and +7 in its compound.
