The total number of isoelectronic species from the given set is ________. O 2 - , F – , Al , Mg 2 + , Na + , O + , Mg , Al 3 + , F

Correct answer

0

Step-by-step solution

Isoelectronic are those which have the same number of electrons. Let us write the number of electrons from the given species. Species No. of electrons O – 2   10 F - 10 Al 13 Mg 2 + 10 Na + 10 O + 7 Mg 12 Al 3 + 10 F 9 Hence five species among the given are isoelectronic species.
