Here's how it works:
* Electrons are transferred: One atom (the more electronegative one) completely takes one or more electrons from another atom.
* Ions are formed: The atom that loses electrons becomes a positively charged ion (cation), while the atom that gains electrons becomes a negatively charged ion (anion).
* Electrostatic attraction: The oppositely charged ions are then attracted to each other, forming a strong electrostatic bond.
Example:
In the formation of sodium chloride (NaCl), sodium (Na) loses an electron to become a sodium ion (Na+) and chlorine (Cl) gains an electron to become a chloride ion (Cl-). The oppositely charged ions attract each other, forming an ionic bond.
Key things to remember about ionic bonds:
* They typically form between metals and nonmetals.
* They result in the formation of crystalline solids.
* They are strong bonds, which means they require a lot of energy to break.
