Question

Write two isoelectronic of f− and cl– ions.

Answer 1

Answer:

(i) F– ion has 9 + 1 = 10 electrons. ... Thus, the species isoelectronic with it will also have 18 electrons. Some of its isoelectronic species are S2– ion (16 + 2 = 18 electrons), Cl– ion (17 + 1 = 18 electrons), K+ ion (19 – 1 = 18 electrons), and Ca2+ ion (20 – 2 = 18 electrons).
