List an element that would have similar properties to Beryllium.
Mg, Ca, Sr, Ba, Ra (any in the same group-2A)
100
Draw the aufbau diagram for Silicon.
1s2 2s2 2p6 3s2 3p2 (there should be 2 unpaired electrons in the 3p orbital)

C-12 (P:6, E:6, N:6) C14 (P:6, E:6, N:8)
200
What group on the periodic table has the most stable electron configuration?
Nobel gases
200
What type of structure do ionic compounds form?
Crystal lattice (alternating ions of opposite charges)
200
List the monomer and polymer for carbohydrates and proteins.
Carbohydrates: monomer-monosaccharide (like glucose), polymer-disaccharide or polysaccharide (like starch) Protein: monomer-amino acid, polymer-polypeptide/protein
200
Write the electron configuration for a Rubidium ion. (Nobel gas shortcut OK, but have one complete energy level)
[Ar]4s2 3d10 4p6 (looks like...)
300
What is the current atomic model called?
Quantum Mechanical Model (orbitals, electrons in energy levels) > a theory, supported by evidence but no proven!
300
Which of the halogens have the largest atomic radius?
Astatine
300
Name the compounds: C4H8 NaBr Sr(SO4) (must get all 3 correct!)
C4H8 -Tetracarbon octahydride NaBr- Sodium bromide Pb(SO4)-Lead (II)Sulfate
300
Which type of radiation can be blocked by a piece of paper?
Alpha
300
Draw the Lewis Dot structure for water.
Two hydrogens bonded to oxygen, two lone pairs on oxygen.
400
Write the alpha decay equation for Ra-222.
Product is Rn-218 + and alpha particle (He nucleus)
400
Which of the Alkaline earth metals have the strongest attraction for electrons?
Be
400
Write the chemical formula AND name: Sulfur ion combines with a Lead 4+ ion.
PbS2 Lead (IV) sulfide
400
What method is best for separating heterogeneous mixtures?
Filtration
400
Different elements emmit different colors of light. Draw a diagram showing WHY this happens. Include LABELS for full credit.
Should include...electron in ground state, excited by heat or energy to excited state. When it falls back down it releases energy in the form of light...a photon.
500
Write the beta decay equation for I-131.
Product is Xe-131 + a beta particle (electron)
500
Which trend(s) INCREASE as you move from metals to nonmetals on the periodic table?
Electronegativity and Ionization Energy
500
Combine and Name the following: 1. Au +2 and S 2. C and F 3. K and hydroxide
1. AuS: Gold (II) sulfide 2. CF4: Carbon tetrafluoride 3. K(OH) Potassium hydroxide
500
List 2 facts about Nuclear Fission and 2 facts about Nuclear Fusion
Fission: fission is breaking apart, large radioisotopes bombarded with neutrons, releases energy Fusion: fusion is combining nuclei, small nuclei like hydrogen combine, happens in the sun, releases MORE energy than Fission
500
Draw Dicarbon tetrahydride. Is this molecule polar or nonpolar?
Carbons should be double bonded :) NONPOLAR.
