The number of \(d\) electrons in Fe is equal to which of the following?
i. Total number of ' \(s\) ' electrons of Mg
ii. Total number of ' \(p\) ' electrons of Cl
iii. Total number of ' \(p\) ' electrons of Ne
The correct option is
- A i, ii only
- B ii, iii only
- C i, iii only
- D \(\mathrm{i}, \mathrm{ii}, \mathrm{iii}\)
Answer & Solution
Correct Answer
(C) i, iii only
Step-by-step Solution
Detailed explanation
Electronic configuration of \(\mathrm{Fe}=[\mathrm{Ar}] 3 \mathrm{~d}^6 4 \mathrm{~s}^2\) \(\therefore \quad\) iron have 6 electron in d orbital Electronic configuration \(\mathrm{Mg}: 1 \mathrm{~s}^2 2 \mathrm{~s}^2 2 \mathrm{p}^6 3 \mathrm{~s}^2\)…
