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.

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.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
