Answer:
Generally, non-metals gain electrons to achieve the octet. This creates a larger negative charge in the electron cloud than positive charge in the nucleus, causing the electron cloud to 'puff out' a little bit as an ion. ... For isoelectronic anions, the more negative the ionic charge, the larger the ionic radius.
