Electronic configuration of d block elements -

These elements have other electronic configuration of   (n-1)d^{1-10}ns^{1-2}

-

 

 Ti (22) = 1S ^{2} 2S^{2} 3S ^{2} 3p ^{6} 4 S ^ {2} 3d ^{2}

correct order is 3s 3p 4s 3d


Option 1)

3s 4s 3p 3d

This option is incorrect

Option 2)

4s 3s 3p 3d

This option is incorrect

Option 3)

3s 3p 3d 4s

This option is incorrect

Option 4)

3s 3p 4s 3d

This option is correct

NEET 2024 Most scoring concepts

    Just Study 32% of the NEET syllabus and Score up to 100% marks

According to afbau rule..

The higher the value of n+L the higher the energy.., if they have same n+L value.. The lower n value  orbital  has less energy.. 

In the above options.. n+L values as follows.. 

3s = 3+0 = 3

4s = 4+0 = 4

3d = 3+2 = 5

3p = 3+1 = 4

So, the correct order of increasing energy is  3s < 3p < 4s < 3d..
