They don't share and both deal with only 1 electron.
Lithium gives away 1 electron.
F will receive that electron.
The chemical formula is LiF
You can automatically rule out CH₄ since it has no lone pairs at all around the central atom. Water has 2. Ammonia is the only Lewis structure that contains one lone pair.
