Question

When an ionic bond forms between lithium (Li) and fluorine (F), which of the following occurs?

F loses one electron.
F loses two electrons.
F gains one electron.
F and Li share electrons.

Answer 1

F gains one electron.

Step-by-step explanation:

Hello,

Due to the high electronegativity of the fluorine atom (approx 3.98), it tends to gain electrons rather than lose them. Now, as lithium has the following electron configuration:

`1s^22s^1`

It loses one electron that is gained by the fluorine to form lithium fluoride, LiF.

Best regards.

Answer 2

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
