Electron configuration of fluorine

Electronic configuration of fluorine is 1s² 2s² 2p⁵.

Electronic configuration can be characterized as follows:

Fluorine (F) has an atomic number of (9).

Based on the rules of electron configuration, fluorine contains 9 electrons dispersed across several shells, subshells, and orbitals.

Shells:

A fluorine atom has two shells:

The initial shell (K shell) can only accommodate two electrons at a time.
Eight electrons can fit in the L shell, which is the second shell, at most.

Sub-shells:

There are various sub-shells within each shell, identified by letters:

One subshell, designated as 1s, belongs to the K shell.
The two subshells of the L shell are designated as 2s and 2p.

Orbitals:

Orbitals, which stand for the areas of space where electrons are most likely to be located, are further separated into sub-shells. Maximum capacity for each orbital is two electrons.

1s orbital:

The 1s orbital is the only orbital in the 1s subshell. Maximum capacity is 2 electrons.

2s orbital:

The 2s orbital is the only one in the 2s subshell. Additionally, it can only hold up to two electrons.

Table of Electronic configuration of fluorine

Shell	Sub-shell	Orbital	Number of Electrons
K	1s	1s	2
L	2s	2s	2
	2p	2px, 2py, 2pz	5

Note:

3 orbitals make up the 2p sub-shell, designated as 2px, 2py, and 2pz. These orbitals can each accommodate a maximum of two electrons.Let’s now fill the orbitals with electrons in accordance with fluorine’s electron configuration:
