Ionic bonding is a type of chemical bond that occurs between two atoms when one atom transfers electrons to another. This process typically happens between a metal and a non-metal. The metal atom loses one or more electrons, becoming a positively charged ion, while the non-metal atom gains those electrons, becoming a negatively charged ion. The opposite charges of these ions create an attractive force that holds them together. This bond results in the formation of ionic compounds, such as sodium chloride (table salt). Ionic compounds usually have high melting and boiling points and can conduct electricity when dissolved in water.
