The total number of isoelectronic species from the given set is________.
O 2- , f - , Al, Mg 2+ , Na + , O + , Mg, A1 3+ , F
Text Solution
Verified by ExpertsThe correct answer is:
5
(5) 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
A1 3+ 10
F 9
Hence five species among the given are isoelectronic species.
