List the energy levels for the orbital configuration of vanadium atomic 23

The electron configuration for Vanadium : 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d³

Given

Vanadium with atomic number=23

Required

Orbital configuration

Solution

The energy level is expressed in the form of electron configurations.  

There are 4 sub-shells in the shell of an atom, namely s, p, d and f. The maximum number of electrons for each sub shell is  

• s: 2 electrons  

• p: 6 electrons  

• d: 10 electrons and  

• f: 14 electrons  

Charging electrons in the sub shell uses the following sequence:  

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.

For Vanadium :

energy level = n

n=1,first energy level : 1s²

n=2,second energy level : 2s², 2p⁶

n=3,third energy level : 3s², 3p⁶, 3d³

n=4,fourth energy level :  4s²
