Here are some examples of binary ionic compounds:
* NaCl (Sodium chloride - table salt)
* KBr (Potassium bromide)
* CaO (Calcium oxide)
* MgCl₂ (Magnesium chloride)
* Al₂O₃ (Aluminum oxide)
* LiF (Lithium fluoride)
Key Characteristics of Binary Ionic Compounds:
* Metal and Nonmetal: They are composed of a metal cation (positively charged ion) and a nonmetal anion (negatively charged ion).
* Electrostatic Attraction: The ions are held together by strong electrostatic forces of attraction.
* Neutral Charge: The compound overall has a neutral charge, meaning the positive and negative charges balance out.
* Crystalline Structure: They usually have a regular, crystalline structure.
* High Melting and Boiling Points: Due to the strong ionic bonds, they have relatively high melting and boiling points.
Remember: Binary ionic compounds do not include compounds with polyatomic ions (like sulfates, nitrates, etc.).
