SCANTRON – Questions from alloy lab see the questions on the lab page – many of them are on the test.

draw lewis structures for water, CF₄, CaI₂, sodium sulfide

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.
