Ionic+Compounds

Ionic bonds are formed when electrons transfer from one neutral atom to another. Ionic compounds are generally made up of positively charged cations and negatively charged anions. Generally ions are combinations of metals and non metals where the cation is a metal and the anion is a nonmetal. Because ionic compounds are formed by resolving separate charge imbalances,positive positive and negative negative bonds cannot occur. Ionic compounds have either a positive or negative charge depending on whether there is an excess of protons or electrons. The ionic compounds are held together in structures called lattices.
 * __Ionic compounds__** are composed of ions held together by electrostatic forces called ionic bonds.

Sodium Chloride. 1. Sodium and Chlorine are both neutral atoms. 2. An electron is transferred from the Sodium atom to the Chlorine atom, producing a positively charged Sodium atom and a negatively charged CHlorine atom. 3. Opposite charges attract, an ionic bond is formed and the result is the ionic compound NaCl. 
 * __Example of Forming an Ionic Compound__**



A lattice of NaCl. The green atoms are Chloride( Cl− ) and the purple are Sodium( Na+ ).
