Which one of the following general electronic configurations <strong>CORRECTLY</strong> represent a transition metal element?
- A. (n-2)d^{1-10}ns^2
- B. (n-2)f^{1-14}(n-1)d^{0-1}ns^2
- C. ns^2np^6nd^{1-10}
- D. (n-1)d^{1-10}ns^{0-2} ✓
Correct Answer: D. (n-1)d^{1-10}ns^{0-2}
Explanation
Transition metals are d-block elements, and their general outer electronic configuration is given by (n-1)d^{1-10}ns^{0-2}.
