Question: 1 / 400

What is an ionic bond?

A bond formed through the sharing of electrons

A bond formed through the transfer of electrons between atoms

An ionic bond is characterized by the transfer of electrons between atoms, leading to the formation of charged particles called ions. In this type of bond, one atom (usually a metal) donates one or more electrons to another atom (usually a non-metal), resulting in a positively charged ion (cation) and a negatively charged ion (anion). The electrostatic attraction between these oppositely charged ions creates the ionic bond, resulting in the formation of ionic compounds.

This bonding type is distinct from covalent bonds, where electrons are shared, and it plays a crucial role in the formation of many compounds, particularly salts. The transfer of electrons leads to stable electronic configurations for both participating atoms, which is why this bonding method is prevalent in the formation of stable compounds.
