Chapter Overview

The valence electrons of an atom can be shown with the use of an electron dot diagram. Ions form in order for atoms to obey the octet rule. Metal atoms lose electrons, while nonmetal atoms gain electrons. Transition metal atoms often cannot lose enough electrons to obtain a noble gas electron configuration. The transfer of one or more electrons from a metal atom to a nonmetal atom results in an ionic bond between the two oppositely charged ions. Ionic compounds have specific properties such as hardness and brittleness that result from the ionic bonding and crystalline structure. Pure metals also adopt a crystalline structure where valence electrons are delocalized and can move around the stationary metal cations.
