False. The F- and O2- ions do not have the same electron configuration.

The F- ion has gained one electron compared to the neutral fluorine atom (F). Therefore, it has the electron configuration of 1s2 2s2 2p6, just like the noble gas neon (Ne).

On the other hand, the O2- ion has gained two electrons compared to the neutral oxygen atom (O). Therefore, its electron configuration is 1s2 2s2 2p6, which is the same as the noble gas neon (Ne) as well as the F- ion.
