Fluorine has 7 valence electrons. Which of the following is true of a fluorine molecule (F2)?
a: A pair of electrons will be shared between the fluorine atoms.
b: Only 4 valence electrons will travel around each fluorine atom.
c: Twelve valence electrons will travel around each fluorine atom, but only 2 will remain around the respective atoms.
d: Each fluorine atom will take 1 valence electron from the other, and this will constantly happen back and forth.

Hello and welcome to OpenStudy! First, what do you think? You already know the atoms have 7 valence electrons so they only need one more.

im not sure I've been working a lot and missed a lot of my chem. classes but now im backed up in work and a little confused!

Here is a hint: there is no electron transfer.

okay so I think its A.

Sounds right :) Also, I think it is helpful to remember that group 19 elements usually exist as diatomic molecules sharing a pair of electrons between them. Also, if you are satisfied, please close this question. And do make time to read our CoC: http://openstudy.com/code-of-conduct Welcome to OS again and enjoy your stay!
