Net Ionic Equation Definition. The net ionic equation is a chemical equation for a reaction which lists only those species participating in the reaction. The net ionic equation is commonly used in acid-base neutralization reactions, double displacement reactions, and redox reactions.
IONIC BOND. The ionic bond is the electrostatic force of attraction between two oppositely charged ions i.e., a positively charged cation and a negatively charged anion. It is formed due to complete transfer of electrons from one atom to another atom. The steps involved in the formation of ionic bond can be summarized as: 1  a) An electropositive atom (metal) loses electron(s) to form a positively charged ion called as cation. 2  b) An electronegative atom accepts the electron(s) to form a negatively charged ion, otherwise known as anion.
