The size of the Radius of a positve ion is smaller than a neutral atom because the postive ion has lost electrons, which means the outer most shell might be lost as well making the positve ion smaller and the nuetral atom remains the same

∙ 15y ago"The trend of smaller atoms across a period is caused by the increasing positive charge of the nucleus, which attracts electrons towards the nucleus." The attraction would then decrease the radius in a cation (positive ion). A neutral atom has no charge. Thus, the radius remains the same.

∙ 15y agoA positively charged atom has one less electron than it should. Thus, there is less sheilding of the nucleus. THUS, as wierd as it may seem, if you take away one electron, the nuclear radius gets bigger as there is less 'pressure' by the electrons pushing in on the protons of the nucleus.

∙ 13y agoThe radius of a positive ion is less than the radius of an atom from which it can be derived.
Wiki User
∙ 12y agoNo, its size can vary depending on how many positive charges are in it.
Wiki User
∙ 8y agoFor the positive ion the radius is smaller; for the negative ion the radius is bigger.

∙ 12y agoThat depends on which ion.

When an atom becomes a cation what happens to it's radius?
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.
How does the ionic radius of a typical anion compare with radius for corresponding neutral atom?
The anion is bigger. Because in an anion there are more electrons than protons in the nucleus, making the pull on the electrons weaker.
How does the size of a negative ion compare to the size of the atom that formed it?
A cation is smaller than the neutral atom because one electron is removed from the original atom to form it. An anion is larger than the neutral atom because one electron is added to the original atom to form it.
If an electron is added to a neutral atom the atom becomes what?
it will become a negative ion due to the negative charge of electron
How does a plus exponent change the atomic radius?
A cation has a smaller atomic radius compared with the neutral atom.
Compare the number of electrons of a negative ion to that of the neutral atom include both negative ion and neutral atom in your answer?
The total charge of atoms is equal to the number of positive protons balanced by the total number of negative electrons in a neutral atom which balances the number of electrons.
What is bigger a neutral atom or a negative atom?
neutral atom
What occurs to the radius when an atom loses an electron?
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.
How does the ionic radius of a typical anion compare with radius for corresponding neutral atom?
The anion is bigger. Because in an anion there are more electrons than protons in the nucleus, making the pull on the electrons weaker.
How does the size of a cation compare with the size of the neutral atom from which it is formed?
An ion is an atom that carries a charge because it has more or less electrons than its neutral form. An electron weighs less than 0.06% of a proton and doesn't take up any real space, therefore an ion is not different in size than its neutral atom.
Is a atom positive or negative?
neither, its neutral
Is the shell of the atom neutral positive or negative?
An atom can be neutral or electrically charged (anion-negative charge, cation-posititve charge); the electrons are negative charged elementary particles.
How does the size of a negative ion compare to the size of the atom that formed it?
A cation is smaller than the neutral atom because one electron is removed from the original atom to form it. An anion is larger than the neutral atom because one electron is added to the original atom to form it.
Does chlorine atom has a smaller radius than chlorine ion?
Yes, considerably so. In general, positive ions are smaller than their neutral atoms, and negative ions are larger than their neutral atoms.
Is chlorine positives or negative?
The atom is neutral; the ion chloride is negative.
