Chemical Bonds

Chemical Bonds. Chapter 8. A Chemical Bond is a link between atoms. An Ionic Bond is the electrical attraction between the opposite charges of cations and anions. A Lewis symbol consists of the chemical symbol of an element and a dot for each of its valence electrons.Example He:

Complex Ion Formation

transition metals tend to be good Lewis acids they often bond to one or more H 2 O molecules to form a hydrated ion H 2 O is the Lewis base, donating electron pairs to form coordinate covalent bonds Ag + ( aq ) + 2 H 2 O( l ) ? Ag(H 2 O) 2 + ( aq )
