If you think about it, the metallic or covalent radius is going to be a measure of the distance from the nucleus to the electrons which make up the bond.
The ionic radius is the distance between the nucleus and the electron in the outermost shell of an ion. When an atom loses an electron to form a cation, the lost ...
To derive ionic radii, it is assumed that the individual ions are spherical and in contact. The radius of one commonly occurring ion, such as the oxygen ion, O2À, ...
The edge of the unit cell is twice the radius of a Mg2 ion (2 times 79 pm) plus ... An ionic compound of formula MX and based on a face-centered cubic lattice of X ...
