The correct electron configuration of Phosphorus (P) :
1s², 2s², 2p⁶, 3s², 3p³ or [Ne] 3s²3p³
Further explanation
Given
Phosphorus (P) element
Required
The correct electron configuration
Solution
The electron configuration of an element is primarily based on the number of electrons
Phosphorus (symbol P) has the atomic number 15
The atomic number itself shows the number of electrons and the number of protons of an atom.
atomic number = number of electrons = number of protons in neutral atoms
So that the number of electrons from Phosphorus = 15
Its electron configuration :
1s², 2s², 2p⁶, 3s², 3p³ or [Ne] 3s²3p³
