It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
When an atom transfers/ gains a valence electron, it gains either a positive or negative charge. in the Proces, becoming an ion. because of the negative/positive charge the two ions are now attracted to each other.
