Unformatted text preview: Chem 1075 Chapter 12 Chemical Bonding Lecture Outline Slide 2 Chemical Bond Concept • Recall that an atom has ___________and _________________electrons. • Core electrons are found _________________ to the nucleus. • Valence electrons are found in the ________________________ s and p energy subshells. • It is ___________________ electrons that are responsible for holding two or more atoms together in a _______________________________________. Slide 3 Octet Rule • The _________________________ states that atoms bond in such a way so that each atom acquires _____________ electrons in its outer shell. • There are two ways in which an atom may achieve an octet. (a) By _____________________of electrons from one atom to another (b) By _________________________ one or more pairs of electrons Slide 4 Types of Bonds • Ionic Bonds are formed from the ___________________________________ of electrons between atoms to form ________________ compounds. • Covalent Bonds are formed when two atoms __________________ electrons to form ____________________________________compounds. Slide 5 Ionic Bonds • An ionic bond is formed by the _____________________ between ____________________ charged cations and _________________ charged anions. • This ______________________________________is similar to the attraction between opposite poles on two magnets. Slide 6 Ionic Bonds • The ionic bonds formed from the combination of anions and cations are _____________________________ and result in the formation of a rigid, ________________________ structure. The structure for ____________ ordinary table salt, is shown here.
