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