Chenmical Bonding *Modified Slide
•Determined by
the # of e- in the outermost shell (valence
electrons)
•Positively
and negatively charged ions attract each other to
form an Ionic bond —Cations, Anions (atoms
lose or gain e-)
•In the body,
ionic bonds are found mainly in teeth and
bones
•An ionic
compound that dissociates in water into + and -
ions is called an electrolyte
–the solution can conduct an electric current
