F2
2 atoms per molecule
6.02 * 10^23 molecules/mole * 2 atoms/molecule =
1.2 *10^24 atoms/mole

Because F is diatomic, it only exists as F2.
1 mole equals 6.023 x 10 to the 23.
Now because you have a diatomic molecule you need to multiply 2x 6.023 x 10 to the 23 to obtain the number of atoms of F per mole.

2 x (6.02 x 10^23) = 1.20 x 10^24 atoms
As Rajpreet points out, fluorine is F2, so 2 atoms/mole. Darling seems unaware of this.

I think it's 6.022e23 * 2 because you do: 1mol F times 6.022e23 molecules/1mol. The moles cancel, and you're left with 6.022e23 molecules of F2. So you multiply by 2 to get the amount of F atoms.

Do you know Avogadro Number ?
If not then read
It is the no. of atoms or molecules in one mole of a substance.
its value is 6.023*10^23
this is the no. of atoms in 1 mol of fluorine

F is a diatomic gas. basically it only comes with a buddy.
F2
so in one mol, you have 2 Fs
