Well, given that selenium has a #+2# charge as a group 16 metal(-ish; the melting point is high but the electronegativity is medium), it must be bonding with two fluorides.

What is the charge on fluoride? Look at what column fluorine is in.

Knowing that, how do you explain that two fluorides pair up with one selenium, giving selenium difluoride?
