Which of the following has the largest atomic radius: f-, f, cl-, or cl?

Option (c) is the correct answer.

Explanation:

More is the number of electrons present in an atom more will be its atomic size.

Atomic number of fluorine is 9 which means in neutral state a fluorine atom has only 9 electrons.

But when one electron is gained by a neutral fluorine atom then it changes into ion and there will be a total of 10 electrons in it.

On the other hand, atomic number of chlorine is 17 which means in neutral state a chlorine atom has only 7 electrons.

And, when this neutral chlorine atom gains an electron then it will form ion. Hence, total number of electrons present in a ion is 18.

Therefore, a ion has more number of electrons that is, 18 out of the given species.

Thus, we can conclude that atomic radius of ion is the largest.

i'm assuming that the correct answer is indeed the first one/ "a"..

1 is the answer to this problem
