Ion sizes are measured by the ionic radius.Ionic Radii in PicometersThe gray color in the diagrams shows the size of the original atom. The blue (cation) and yellow (anion) shows the size of the ion. (Diagrams b
Ionic radius increases moving down a group because the number of electron orbitals increases in number moving into higher and higher periods. Typically, an atom with a high number of electron orbitals will have a larger atomic radius, and therefore will likely have a large ionic rad...
Measurement of an ionic species: We measure the ionic species by their ionic radius. Usually, the radius of cations is lesser (nearly <10-10 m) than that of anions. This is the reason that anions occupy most of the space in crystals while cations occupy only minimal space due to their ...
Important properties that display periodicity include ionization energy, electronegativity, atomic radius, and electron affinity. Periodicity Definition In the context of chemistry and theperiodic table, periodicity refers to trends orrecurringvariations inelementproperties with increasingatomic number. Periodicity...
each other. In this context, "touching" means the outermost electron shells are in contact with each other. Theionic radiusis another method of estimating atom size. The ionic radius is half the distance between two atoms touching each other in a crystal lattice (atoms forming an ionic bond)...

The octet rule in chemistry is the principle that bondedatomsshare their eight outerelectrons. This gives the atom a valence shell resembling that of a noble gas.The octet ruleis a "rule" that is sometimes broken. However, it applies to carbon, nitrogen, oxygen, the halogens, and most met...
This is the definition of an ionic bond in chemistry as well as examples of compounds that contain this type of chemical bond.
