#1 – We Are Family
A. Colour and label the families on the periodic table (halogens, chalcogens, nobel gases, transition metals, alkali metals, alkaline earth metals).
B. Use a marker to draw in the stair case, signifying the metalloids.
#2 – But WHY?
Answer the following questions. Consider their properties and how many valence electrons they have.1. What is the octet rule?2. What is so special about the metalloids?3. Why are alkali metals the most reactive metal?4. Why are halogens the most reactive nonmetal?5. Why are the noble gases (basically) nonreactive?6. Which element would you expect to lose 3 electrons? Why
would it gain instead of lose?7. Which type of elements gain electrons?8. Which type of elements lose electrons?
#3 – I’ve Got My ION You
Use Lewis Dot Diagrams and ionic charges to explain each of the following:1. How does a sodium atom become a sodium
ion? What kind of ion is this? 2. How does an oxygen atom become an oxygen
ion? What kind of ion is it?3. How do you know the ‘charge’ on an ion?4. Explain how to find out the chemical formula if
you mixed sodium with oxygen.
#4 – That’s Not My Name
• Name the following compounds and identify them as ionic or covalent:1. SiF4 6. SO2
2. NaBr 7. NaF3. N2S3 8. MgCl2
4. Br2 9. V2O5
5. K3N 10. Cu2S
#5 – Which Is Better
• Complete the table in your book comparing ionic and covalent compounds.
• Once you have completed the table, answer the following question about a hypothetical relationship.– If you were in a romantic relationship, would you
want it to be ionic or covalent, and why?
#6 – Kindergarten Cop
• Answer the following questions:- What is a single bond?- What is a double bond?- What is a triple bond?- Why are two bonded nonmetals are never ionic?
Explain.
#7 – Balancing Act
• Answer the following questions:– What is the law of conservation of mass?– Why does it apply to chemical reactions, such as
the following? N2 + H2 NH3
– Is this reaction balanced?– How do you know if a chemical reaction is
balanced?
#8 - Multiplicity
• Balance the following reactions:
a. ____ K + ____ MgBr ____ KBr + ____ Mg
b. ____ H2O + ____ O2 ____ H2O2
c. ____ NaBr + ____ CaF2 ____ NaF + ____ CaBr2
d. ____ H2SO4 + ____ NaNO2 ____ HNO2 + ____ Na2SO 4
e. ____ S8 + ____O2 ____ SO3
f. ____ Na + ____ H2O ____ NaOH + ____H2
#9 – Are You My Mother?
• Identify the following reactions as either combustion, neutralization, single replacement, double replacement, synthesis or decomposition.
a. NaBr + Ca(OH)2 CaBr2 + NaOH
b. C5H10 + O2 CO2 + H2O
c. Pb + H3PO4 H2 + Pb3(PO4)2
d. NH3+ H2SO4 (NH4)2SO4
e. HCl + NaOH --> NaCl + H2O
#10 – Creation
• Write 3 questions that you would expect to see on the test on a cue card with the answers on the back.– One question – true or false– One question – multiple choice– One question – short answer
