INFORMATION:
We must determine what involves an ionic bond
STEP BY STEP EXPLANATION:
To determine it, we need to know that:
In ionic bonding, one atom loses valence electrons and gains them from another. For both atoms involved, this exchange results in a more stable noble gas electrical state. The attractive electrostatic interactions between two ions of opposite charge form an ionic bond.
Finally, knowing that, we can say that an ionic bond involves a transfer of electrons.
ANSWER:
b. a transfer of electrons.
