Why do some atoms gain electrons and other atoms lose electrons during ionic bonding?

Answer 1

be

cause

electron gaining atom is placed far to the atom s nueclius so that it does NT attract that at all ,&it escapes from the outermost orbital..........

Answer 2

Atoms gain or lose electrons during ionic bonding to achieve a stable outer electron configuration resembling that of a noble gas. Atoms with few valence electrons tend to lose electrons to attain a full outer shell, while those with almost full shells tend to gain electrons. This transfer allows atoms to achieve a more stable electronic configuration.
