For a unielectronic spiecie , compere the energy of the following orbitals (represented by S)
`S_(1)`= a spherically symmentrical orbital having two spherical nodes.
`S_(2)`= an orbital which is double -dum bell ans has no radial nodes. lt brgt `S_(3)` an orbital with orbital angualr momentum zero and three rodal nodes.
` S_(4)` an orbita, having one planner and one radial node.

Options

A. `S_(1)=S_(2)=S_(3)=S_(4)`
B. `S_(1)=S_(2)=S_(4)ltS_(3)`
C. `S_(1)gtS_(2)gtS_(3)gtS_(4)`
D. `S_(1)ltS_(2)ltS_(3)ltS_(4)`

Answer

B

Explanation

`S_(1)to 3s`
`S_(2)to 3d`
`S_(3)to 4s`
`S_(4)to 3p ` for uncielectron species energy depends only on" 'n'
`therefore` `S_(1)=S_(2)=S_(4)ltS_(3)`
