NEETChemistryStructure of AtomMCQ+4 / −1
If n = 6, the correct sequence for filling of electrons will be
  1. A
    ns→(n−2)f→(n−1)d→npns \to \left( {n - 2} \right)f \to \left( {n - 1} \right)d \to npns→(n−2)f→(n−1)d→np
  2. B
    ns→(n−1)d→(n−2)f→npns \to \left( {n - 1} \right)d \to \left( {n - 2} \right)f \to npns→(n−1)d→(n−2)f→np
  3. C
    ns→(n−2)f→np→(n−1)dns \to \left( {n - 2} \right)f \to np \to \left( {n - 1} \right)dns→(n−2)f→np→(n−1)d
