2015 · Q93

NEETChemistryStructure of AtomMCQ+4 / −1
The number of d-electrons in Fe2+ (Z = 26) is not equal to the number of electrons in which one of the following ?
  1. A
    d-electrons in Fe (Z = 26)
  2. B
    p-electrons in Ne (Z = 10)
  3. C
    s-electrons in Mg (Z = 12)
  4. D
    p-electrons in Cl(Z = 17)
View written solutionFree

Correct answer: D
