Answer
Electronic configuration of 8B is [2, 6]. It needs two electrons to complete its octet.
Electronic configuration of 20A is [2, 8, 8, 2]. It wants to donate two electrons in order to obtain a stable octet configuration.
Hence, ionic bond is formed as 20A loses two electrons and 8B gains two electrons and both attain a stable octet.
8B [2, 6] is present in group VIA and 20A [2, 8, 8, 2] is present in group in IIA as the group of an elements is predicted from the number of electrons in the valence shell.
