Ion sizes are measured by the ionic radius. Ionic Radii in Picometers The 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 by Chris King.) Ionic Compounds Ionic compounds, such as sodium chloride ...
Crystals of sodium chloride, NaCl, magnified. Electric Conductivity In general, ionic solids do not carry electric current, because the ions are in fixed positions in the crystal lattice. They do, however, conduct electricity when molten or when dissolved in solution, when the ions are released ...
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...
Give a good definition for the term ''ionic bond'' when it comes to structures and bonding in chemistry. Chemical Bond: A chemical bond is an attractive force between two atoms that holds them together in a molecule and stabilizes them. Chemical bonds can be...
Atomic Radius- This is half the distance between the middle of two atoms just touching each other. Atomic radius decreases moving left to right across a period and increases moving down a group. Ionic radius is the distance for ions of the atoms and follows the same trend. Although it might...
The diameter of an atom is on the order of 1 angstrom, so the unit is particularly handy when referring to theatomic and ionic radiusor size of molecules and spacing between planes of atoms in crystals. The covalent radius of atoms of chlorine, sulfur, and phosphorus are about one angstrom...
Measurement of an ionic species:We measure the ionic species by theirionic 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 smal...

An atom will have different radii depending on the bond it forms, so there is no fixed radius of an atom. Atomic Radii are therefore determined by the bonds they form.
Chemistry DictionaryDefinition of Ionic Bonding What is Ionic Bonding? Chemical bonds form when the total energy of the bonded atoms is lower than the total energy of the separate atoms. The form the bonding takes is determined by the electron arrangement that minimizes the energy. In some ...
