chemistry

$H^- > H^+ > H$

$Na^+ > F^- > O^{2-}$

$F^- > O^{2-} > Na^+$

$Al^{3+} > Mg^{2+} > N^{3-}$

Explanation

To determine the correct order of ionic radii, we need to consider the following principles: $\\$ • Ionic radius generally increases with increasing negative charge (more electrons) and decreases with increasing positive charge (fewer electrons). $\\$ • For isoelectronic species (ions with the same number of electrons), the ionic radius decreases with increasing nuclear charge (more protons). $\\$ Let's analyze each option: $\\$ Option 1: $H^- > H^+ > H \\$
