Answer:
The answer to your question is Ionic bonding.
Explanation:
There are three main types of bonding:
- Ionic bonding is when a metal attaches to a nonmetal and the electronegativity is higher than 1.7.
- Covalent bonding is when a non metal attaches to another non metal. and the electronegativity is between 0 and 1.7.
- Metallic bonding is a bond between metals.
In this question, we have Lithium plus fluorine
Formula LiF
In this compound there a metal and a nonmetal
Electronegativity Fluorine = 3.98 Lithium = 0.98
Difference of electronegativity = 3.98 - 0.98 = 3.0
3.0 > 1.7
Then we conclude that the bond is Ionic.
