Ionic radius is the size of an ion after it has gained or lost electrons, leading to a change in the electron configuration and thus its size. Atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outermost electron shell. Ionic radius is affected by the change in electron configuration, while atomic radius is more related to the position of the outer electrons in the neutral atom.

Does a metal have a greater atomic radius or ionic radius?
A metal typically has a greater atomic radius than its ionic radius. When a metal loses electrons to become a cation, the outer electrons are removed, leading to a decrease in the ionic radius compared to the neutral atom's atomic radius.
What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
How does the ionic radius of a nonmetal compare with its atomic radius?
in the case of non-metals, the anions are formed by the addition of electrons. So the ionic radius is larger than that of the atomic radius
What elements have an ionic radius equal to the atomic radius?
In ionic compounds, the cation typically has an ionic radius smaller than its atomic radius due to the loss of electrons, while the anion has an ionic radius larger than its atomic radius due to the gain of electrons. Therefore, in an ionic compound, the sum of the ionic radii of the cation and anion will generally equal the sum of the atomic radii of the two atoms.
What is the relationship of ionic radius and atomic number?
As you move across a period from left to right, the atomic number increases and the ionic radius decreases. This is because the increase in positive charge in the nucleus attracts the electrons more strongly, pulling them closer to the nucleus, leading to a decrease in ionic radius.

Is H's atomic radius equal to He atomic Radius?
no, as they differ in the number of protons and neutrons

What is hydrogens atomic radius?
* Atomic Radius: 0.79Å * Atomic Volume: 14.4cm3/mol * Covalent Radius: 0.32Å * Ionic Radius: 0.012Å * Atomic Radius: 0.79Å * Atomic Volume: 14.4cm3/mol * Covalent Radius: 0.32Å * Ionic Radius: 0.012Å
What is another word for atomic radius?
The other word for atomic radius includes the Van der Waals radius, ionic radius, and covalent radius. The atomic radius refers to half the distance between the nuclei of identical neighboring atoms in the solid form of an element.
Is metallic radius only for metals?
Yes. There are other measures for ions (ionic radius) and free atoms(atomic radius) and covalent radius. Metallic, ionic and covalent are based on measurements of distances in crystals or covelnt bond lengths, atomic radius is based more on calcuation than observation.

When an atom changes into an ion besides the number of electrons what changes?
The electrical charge; also the ionic radius is different from the atomic radius.
