Fluorine has an atomic number of 9. This means there are 9 protons in the nucleus. Most fluorine around the world has 10 neutrons in the nucleus (mass number of 19).
There will be an equal number of electrons as protons in a normal atom, so 9 electrons. Electrons are arranged with 2 in the first layer closest to the nucleus and 7 in the second layer.
Does this help?
Fluorine is in Group 7A, so it has 7 valence electrons.
The 1s and 2s orbitals are full, but the 2p orbital only has one electron in each subshell.

two.
The first one has 2 electrons.
The second one has 7 electrons.

lithium donates the electron in its outer orbital to fluorine which then has a completed outer shell

Fluorine gas is diamagnetic as there are no unpaired electrons A neutral atom of flurine would be paramagnetic as due to the presence of 1 unpaired electron in a 2p atomic orbital
protons=9 neutrons=9 electrons=9
estoy bien gracias
Fluorine in its elemental stage has 1 unpaired electron. ( 2p5 orbital has one unpaired electron in 2p orbital)

When fluorine (F) takes an electron from sodium (or from any element in an ionic bonding scenario), the 2p6 sub-orbital is filled, which allows fluorine to achieve the electron configuration of nearby neon (Ne).
An orbital diagram is used to show how the orbitals of a subshell areoccupied by electrons. The two spin projections are given by arrowspointing up (ms =+1/2) and down (ms = -1/2). Thus, electronicconfiguration 1s22s22p1 corresponds to the orbital diagram:
it depends on the molecular orbital theory

Both have one electron vacancy in their valency orbital.
