Test Set up –
 Multiple Choice, True/False, Diagram of Periodic Table that you will have to identify specific parts of it
(groups and families and types of elements – metals, nonmetals, metalloids),
 Problems – calculate the wavelength, frequency or energy of light, electron configurations, determine
valence electrons and write dot structures of elements, determine the trends using the periodic table
 Possible short answer questions – Determine the identity of an unknown element using chemical and
physical properties Explain why metals lose electrons and why nonmetals gain electrons.

10 Noble gases are found in group 18 and they are the least reactive elements, Representative elements are
found in groups 1,2 and 13 – 18, the transition elements are found in groups 3 – 12, and the inner
transition elements are found in the two rows below the periodic table
11 a) B 1s22s22p1
b) Mg 1s22s22p63s2 c) As 1s22s22p63s23p64s23d104p3
12 Na, Mg, and Cl are representative elements
14 This is because the outermost electron configuration tells us the block, the row and the number of
elements over in the block that the element is located. For example [Ar] 4s2 tells us that the element is
located in the s-block in row 4 and it is the second one over in the s-block making it the element Calcium
18 a) sodium
b) strontium c) germanium
d) selenium
22 a Sr, Mg, Be b) Cs, Ba, Bi c) Na, Al, S
24 a) Na
b) S2-
c) I -
d) Al
27 a) F
b) N
c) Mg
