(A) Isoelectronic species are those that have the same number of electrons.$O^{2-} = 8 + 2 = 10 	ext{ electrons}$$F^{-} = 9 + 1 = 10 	ext{ electrons}$$Mg^{2+} = 12 - 2 = 10 	ext{ electrons}$$Na^{+} = 11 - 1 = 10 	ext{ electrons}$$Al^{3+} = 13 - 3 = 10 	ext{ electrons}$Other species:$Al = 13 	ext{ electrons}$$O^{+} = 7 	ext{ electrons}$$Mg = 12 	ext{ electrons}$$F = 9 	ext{ electrons}$The isoelectronic species are $O^{2-}, F^{-}, Mg^{2+}, Na^{+}, 	ext{ and } Al^{3+}$.Total count = $5$.

The total number of isoelectronic species from the given set is $.......$
$O^{2-}, F^{-}, Al, Mg^{2+}, Na^{+}, O^{+}, Mg, Al^{3+}, F$
