Compare ionic, covalent, and metallic bonding in terms of outer electrons & element type
Predict type of bond ionic, pcovalent, npcovalent, metallic, or not possible:
Pb-S, K-Cl, N-O, Ar-I, N-N
Polyatomic means _______ atoms, ion means __________. So a polyatomic ion is
A molecule is
How are polyatomic ions and molecules alike and different?
How is electronegativity related to bonding?
What is the difference between p and np covalent bonding?
What is the difference between a formula unit and a molecule in terms of bonding?
What is the difference between electron dot and lewis structures?
Why don’t noble gases bond?
What determines the central atom in a lewis structure?
What is the octet rule? What elements fulfill it without help?
Predict what each atom will do to become stable, and then give resulting ionic charge:
Al Co Mg Xe P I K
Draw dot diagrams for each of the above atoms
__________ bonds are malleable because of delocalized electrons,
__________ bonds the strongest, resulting in brittle crystals like salt (NaCl).
_________ bonds as found in water and methane (CH4),
are often found in substances that are in the ________ or _______ state of matter.
