Pure substances may be either elements (all atoms alike) or compounds (different atoms combined in molecules of definite proportions and inseparable by physical means). –Ionic compounds are composed of positive and negative ions (atoms with extra or fewer electrons than their neutral counterparts) –Molecular compounds are composed of neutral atoms which are held together by sharing some of their electrons in common http://www.chemtopics.com/lectures.htm
