Study Notes
Ionic Compounds Overview
- Ionic compounds consist of two or more ions bonded through electrical attraction, with one ion carrying a positive charge (cation) and the other a negative charge (anion).
- Cations typically originate from metal atoms, while anions are usually nonmetals or polyatomic ions, which consist of multiple atoms.
Properties of Ionic Compounds
- All ionic compounds crystallize, forming structured lattice arrangements.
- They exhibit high melting and boiling points due to the strong electrostatic forces between ions.
- Ionic compounds are characterized by hardness and brittleness, making them resistant to deformation.
- Electrical conductivity is observed in ionic compounds when they are dissolved in water, due to the mobility of ions.
Additional Facts about Ionic Compounds
- Metal cations predominantly bond with nonmetal anions to form ionic compounds; ammonium ion is a notable exception, acting as a cation without containing metal.
- Ions achieve stability by satisfying the octet rule, which involves having eight electrons in their outermost shell.
