The charges of a set of isoelectronic ions vary from 3+ to 3-. Place ions in order of increasing size.?

Answer 1

atoms of positive charge are lighter than negative.

Answer 2

isoelectronic = comparable style of electrons. so , what you're searching for is ions (the two cations or anions) that have an identical style of electrons as xenon. to try this, %. components on the two edge of xenon, and 'eliminate' or 'upload' electrons to cause them to isoelectronic with xenon. for each electron you need to upload to make it isoelectronic, you provide a adverse charge to the atom. for each electron you need to eliminate, you upload a very good charge. some examples(so as of increasing length): La3+
