The anion is bigger. Because in an anion there are more electrons than protons in the nucleus, making the pull on the electrons weaker.
It is larger. Chlorine has a radius of 99 pm and this increases to 167 pm for the ion Cl-
The ionic radius of an anion will be larger than the parent neutral atom.
the positive ionic radius is smaller than the neutral atomic radius
tru
The atomic radius of a cation is smaller than that of its original atom. See the related link for an image example of what this may look like.
The negative ionic radius is larger than the neutral atomic radius
A cation has a smaller atomic radius compared with the neutral atom.
An anion has more electrons than a neutral atom.
the positive ionic radius is smaller than the neutral atomic radius

the bigger the radius the more the mass.
The positive ionic radius is smaller than the neutral atomic radius
The negative ionic radius is larger than the neutral atomic radius
The radius of an anion is bigger than the radius of a neutral atom.
It is about 100,000 times larger
The negative ionic radius is larger than the neutral atomic radius
The diameter of a circle is twice its radius
Equal to the length of the radius.
