1 mol of $\ce{F2}$ is turned into $\ce{2F}$ (atoms).

Is this the specific enthalpy of atomization, or two times that?

Enthalpy of atomisation is energy required to break 1 mole of E-E bonds.

Eg: $\ce{1 F2 -> 2 F}$ .............................$\Delta H_{atomisation}$

Why are you using lower case delta here? Isn't it change in enthalpy, being ΔH? – DarkLightA Mar 22 '13 at 15:30
@DarkLightA I was unable to use it please write a comment without using $ where i can see it's code. – user1395 Mar 22 '13 at 15:47
Right, I was just wondering. I copied that from Wikipedia. – DarkLightA Mar 22 '13 at 16:00
Use Delta, not delta in the Tex. – Alyosha Mar 22 '13 at 18:39

ChemGuide says that 'The standard atomisation enthalpy is the enthalpy change when 1 mole of gaseous atoms is formed from the element in its standard state.'

For example,
