Which of the following correctly compares the radii of F and F−? (5 points)

Select one:
a. F has a smaller radius than F− because an additional electron causes greater repulsion in F−.
b. F has a larger radius than F− because an additional electron causes greater repulsion in F.
c. F has a smaller radius than F− because F− has an additional energy shell.
d. F has a larger radius than F− because F has an additional energy shell.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
