Q. The number of unpaired electrons in Fe²⁺ (Z = 26) is:

Fe²⁺ (Z = 26) में अयुग्मित इलेक्ट्रॉनों की संख्या है:

A
Zero
शून्य
B
2
C
4
D
6

Explanation

  • Electronic configuration of Fe (Z = 26): [Ar] 3d⁶ 4s²

  • For Fe²⁺, remove two electrons → [Ar] 3d⁶

  • 3d⁶ has 4 unpaired electrons in a high-spin configuration (according to Hund’s Rule).
