Which transition metal does not form 'MO' type oxide? ( \(\mathrm{M}=\) transition metal)
- A V
- B Cr
- C Mn
- D Sc
Answer & Solution
Correct Answer
(D) Sc
Step-by-step Solution
Detailed explanation
Sc , electronic configuration \(=1 \mathrm{~s}^2 2 \mathrm{~s}^2 2 \mathrm{p}^6 3 \mathrm{~s}^2 3 \mathrm{p}^{\circ} 4 \mathrm{~s}^2\) \(3 \mathrm{~d}^1\) to form the oxide Sc have to remove 20 electrons from its d and s-orbital. It form a very unstable configuration. Sc will…
