QJEEM04Ch4696: JEE Main 2004 Chemistry - Class 11 JEEM04Ch4696 Solution: Consider the ground state of Cr atom (Z = 24). The number of…

Consider the ground state of Cr atom (Z = 24). The number of electrons with the azimuthal quantum numbers, l = 1 and 2 are respectively

Multiple Choice Options

  • A 16 and 4
  • B 12 and 5
  • C 12 and 4
  • D 16 and 5

Step-by-Step Verified Solution

Electronic configuration of Cr (Z = 24) =

1s2 2s2 2p6 3s2 3p6 4s1 3d5

For 2p6 and 3p6 , l = 1. Here in 2p and 3p orbital total 6 + 6 = 12 electrons present.

For 3d5 , l = 2. Here in 3d orbital total 5 electrons present.
