Be able to: write electron configurations, noble gas electron configurations, draw orbital diagrams, exceptions
to normal electron configurations, calculate wavelength, frequency, energy and relate each other.
 Alkali metals, alkaline earth metals, halogens, noble gases, transition metals, lanthanides, actinides,
metals, nonmetals, metalloids
 Know the properties of metals, nonmetals, and metalloids.
 The trends in the periodic table for atomic radius, ionic radius, isoelectronic series, electronegativity,
ionization energy, and compare atoms vs. ion size for cations and anions. Make sure you know WHY and
Ch. 5 Pg. 146-148
32. light, microwaves, x rays, radio waves
41.the quantum number n specifies the electron’s orbit.
49. b, c are incorrect
52. two electrons
59. Two electrons occupying a single atomic orbital must have opposite spins.
61.Valence electrons are the electrons in the atom’s outermost orbital; 2
70. E= 2.97 x 10 -19 J
72. E= 1.68 x 10 -17 J

33 a. 2
c. 3
36. properties describe a metal; left of the stair step line
40 a. Br, Hg
b. Rn
c. Sn or Pb
d. elements 58-71 or 90-103
42. The number of valence electrons equals the group number for group A elements.

b. Cl: [Ne] 3s2 3p5
c. Li: [He] 2s1
d. Hg: [Xe] 6s2 4f14 5d10
51.because the boundaries of an atom are indistinct
55.Elements on the right side of the periodic table gain electron to gain a stable octet.
59. The group 8A elements have the highest ionization energies because their electron configurations are the
most stable.
63.a. N
b. Ne
C. Li
65 a. the ion is negative. A negative ion is always larger than its own atom.
b. A is to the left of B. Atomic radius in a period decreases from left-to-right
c. A is below B. Ionic radius increases down a group.
66 a.8
76. The element is most likely a nonmetal.
