6. which of the following best to account for the fact that the f-ion is smaller than the 02-ion?
a. f has a larger nuclear mass than 0 has.
b. f has a larger nuclear charge than op has.
c. f is more electronegative than o2-is.
d. f is more polarizable than 02 is.

Answer:

F has a larger nuclear charge thanaccount for the fact that the F-ion is smaller than the -ion

Explanation:

The 'effective nuclear charge' of an  polyelectronic atom, denotes the net positive(+ve) charge that experienced by an electron. The "strength of the nuclear charge" can be determined based on the oxidation-number of an atom which determines the number of electron that is lost or gained by elements.

F-ion is smaller when compared with O2-ion because of the larger nucleus charge of the F-ion. This is because of the presence of more protons in F-ion that pulls the electrons on the shell’s outside, thus making it smaller.
