2.5 The Modern View of Atomic Structure: An Introduction
Objectives: explain bonds hold atoms together in compounds; describe covalent bonds, which hold molecules together; differetiate between chemical formula, structural formula, space fill model and ball and stick formula; explain how an ion is formed; describe the bondig in an ionic compound; differentiate between monatomic and polyatomic ions.
Glossary
space-filling model a model of molecule showing the relative sizes of the atoms and their relative orientations
structural formula a way to represent a molecule in which the individual bonds are shown (indicated by lines)
