Ionic properties

 

 

Molecular properties 		At the beginning of the year we discovered that many compounds can be divided into two broad categories based on a few simple criteria:

ionic compounds
electrons are transferred
generally metals + non-metals
attraction force is opposite charge
"ionic bond"

molecular compounds
outer or valence electrons are shared
generally non-metals only
attraction is simultaneous among electrons and protons of different atoms
"covalent bond"

How do these bonds form and why?
