Here's a breakdown:
* Cations: These are formed when an atom loses one or more electrons, resulting in a net positive charge. Examples include sodium (Na+) and calcium (Ca2+).
* Anions: These are formed when an atom gains one or more electrons, resulting in a net negative charge. Examples include chloride (Cl-) and oxide (O2-).
These oppositely charged ions attract each other, forming a strong electrostatic bond called an ionic bond. The resulting compound is neutral overall, as the positive and negative charges balance out.
Key properties of ionic compounds:
* Solid at room temperature: The strong electrostatic forces hold the ions in a rigid, crystalline structure.
* High melting and boiling points: Breaking the ionic bonds requires a lot of energy.
* Conduct electricity when molten or dissolved in water: Free ions are able to move and carry electric current.
* Brittle: The rigid structure makes them prone to shattering under stress.
Examples of ionic compounds:
* Sodium chloride (NaCl): Sodium (Na+) cation and chloride (Cl-) anion.
* Calcium oxide (CaO): Calcium (Ca2+) cation and oxide (O2-) anion.
* Magnesium sulfate (MgSO4): Magnesium (Mg2+) cation and sulfate (SO42-) anion.
