What is the difference between atomic radii and ionic radii?
Atomic radii refer to the size of an atom, measured as the distance from the center of the nucleus to the outer electron shell. Ionic radii, on the other hand, refer to the size of an ion, which can be larger (anions) or smaller (cations) than the corresponding atom due to the gain or loss of electrons.
Definition of ionic radii?
Ionic radii refer to the size of ions in a crystal lattice. It is the distance from the nucleus of an ion to its outermost electron shell. Ionic radii help determine the arrangement of ions in a crystal structure and influence the properties of the compound.
Difference between ionic and crystal radii?
Crystal Radii is also known as "Metallic Radii ". It is defined as "half the distance between the nuclei of two adjacent metal atoms in the metallic closed packed crystal lattice". It is used for metal atoms which are assumed to be closely packed spheres in the metallic crystal. As for ionic radii .... I don't know.
How do the ionic radii vary within a group of metals?
In a group of metals, ionic radii tend to increase as you move down the group. This is because the outermost electron shell becomes farther from the nucleus as you move down the group, leading to larger atomic sizes and therefore larger ionic radii.
Why must atomic and ionic radii be estimated?
Atomic and ionic radii are estimated because they are not directly measurable quantities. They are theoretical values based on experimental data and mathematical models. Estimating these radii helps in understanding the chemical and physical properties of elements and compounds.
What is the relationship between the atomic numbers and ionic radii of the elements in the group 3A?
I think that the ionic radii decrease

Why are the ionic radii of metallic elements smaller than the atomic radii of the same elements?
The ionic radii of metallic elements is smaller than its atomic radii, because the ion has less electrons. This gives it a smaller electron cloud and makes the atom smaller.

Why are the ionic radii of nonmetallic elements larger than the atomic radii of those elements?
When nonmetallic elements gain electrons to form ions, the additional electrons are added to higher energy levels (shells) farther from the nucleus. This increase in the size of the electron cloud leads to an increase in the ionic radii compared to the atomic radii of those elements.
How is ionic radii measured?
Ionic radii are typically measured using X-ray crystallography or neutron diffraction techniques. In X-ray crystallography, the distance between the nuclei of two ions in a crystal lattice is measured. This distance is then used to calculate the ionic radius.
Are there any trends to the periodic table?
Atomic Radii,Ionic Radii, First Ionization Energy,Second and Higher Ionization Energies, Electron Affinity.
How does ionic radii varie along the period?
The Ionic radii decrease down period until you reach atom that have tendency to become Anion. Then it decreases down the period again for anion as well. For Example, Na+ (99), Mg2+ (72), Al3+ (53), P3- (212), S2- (184), Cl- (181) The value given, in picometers (pm), are ionic radii for the ions.
How do the ionic radii vary within a group of metals how do they vary within a group of nonmetals?
Within a group of metals, the ionic radii generally increase as you move down the group due to the addition of higher energy levels. Within a group of nonmetals, the ionic radii also increase as you move down the group due to the addition of higher energy levels, but they are typically smaller compared to metal ions of the same period.
