15. Ionic bonds result when electrons are between adjacent atoms (ions). a. shared b. lost c. transferred (exchanged) d. stretched and bounced

c. transferred (exchanged)

Explanation:

Ionic bond -

The ionic bond require an anion and a cation, anion is an electron rich atom and the cation is a electron deficient atom,

The formation of an ionic bond is via the transfer of the electron from a electron rich atom to the electron deficient atom.

Hence the correct bond formation for an ionic bond is via transferring of electron.
