Question

What happens when a lithium ion is attracted to a fluoride ion?
a. They form a covalent bond.
b. They form a molecule.
c. They form an ionic compound.
d. They form a solid.

Answer 1

When a metal react with a halogen, the metal tend to lose atom and the halogen tend to accept an atom. Hence, a metal and a halogen forms an ionic bond.

The lithium is a metal and fluorine is a halogen, the lithium donate an electron and the fluorine accepts an atom, and forms an ionic bond, which result in the formation of lithium fluoride.

Hence, the correct answer is:

c. They form an ionic compound.

Answer 2

C. They form an ionic compound!
