Which lanthanoid ions are paramagnetic?

Options

  1. ALa3+ and Ce4+
  2. BYb2+ and Lu3+
  3. CAll except f0 type and f14 type
  4. DAll except Yb2+ and Lu3+

Correct answer

C. All except f0 type and f14 type

Step-by-step solution

The lanthanoid ions other than the f0 type (La3+ and Ce4+) and the f14 type (Yb2+ and Lu3) are all paramagnetic.
