Question 7 of 10 What is the correct electron configuration of phosphorus (P)?
A. 1922s22p%3s 3p
B. 1922s²2p3s 3p4
c. 1s22s22p6206
O D. 1s 2s22p%3s 3p3
SUBMIT

1s2 2s2 2p6 3s2 3p3

Explanation:

The correct electron configuration of Phosphorus (P) :

1s², 2s², 2p⁶, 3s², 3p³ or [Ne] 3s²3p³

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

12 is it do you think so
