What is the difference between atomic radii and ionic radii?
atomci radii measures for an atom ionic radii measures for an ion
Definition of ionic radii?
measure for an ion
Ionic radii of iron?
0.076,0.064 nm
Why were no ionic radii given for He Ne Ar Kr Xe and Rn?
These are the noble gases and since they don't generally form ions, no ionic radii are given.
Why are the ionic radii of the negative ions larger than their corresponding atomic radii?
Because their ability to attract electrons is higher from bottom to top and left to right so the elements on the right side or your negative elements will have a bigger ionic radii

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.

Atomic radii can be measured in?
Picometers, or ! trillionth of a meter.
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.
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.
Why ionic radii of negative ions are larger then the size of their parent atoms?
Because electrons are gained.
