Atoms Molecules Ions Chemical Equations On-line practice



Ionic compounds are formed between metals and non-metals.  The metals usually form the positive ions while the non-metals form the negative ions.

Formation of sodium chloride 

In terms of electron arrangement, the sodium donates its outer electron to a chlorine atom forming a single positive sodium ion and a single negative chloride ion. The atoms have become stable ions, because electronically, sodium becomes like neon and chlorine like argon.
