Chem 2.1 - Ionic Bonding

ionic bond

electrostatic attraction between a metal and a non metal resulting in the complete loss of an electron for the cation and the gain of an electron for the anion.

ions

elements with a charge

redox reaction

formation of an ionic compound from its elements

oxidation

electron loss

reduction

electron gain

transition element

partially filled d level, can form multiple ions with different charges

electronegativity

measure of the ability of an atom to attract a pair of covalently bonded electrons

electronegativity level difference for ionic bonds

greater than 1.8

ionic structure

lattice structure, a network of repeating ions, non-directional

volatility of ionic bonds

low due to strong electrostatic forces

melting and boiling point of ionic bonds

high due to strong bonds

electrical conductivity of ionic bonds

poor in solid compounds due to lack of mobile electrons

solubility of ionic bonds

soluble in polar solvents
