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.  

the answer

explanation:

the capillary tube was too close to the bottom of the beaker.

the ruler may have moved.

water got into the capillary tube.

the temperature was not allowed to equilibrate in the 2-4 minutes.

i can ! i just need to know what the paragraph is! : p
