Here are the answers to the questions on your worksheet.
1) List the symbols of the elements in Period 2.
Li, Be, B, C, N, O, F, Ne
2) List the atomic numbers of the elements in Period 2.
3, 4, 5, 6, 7, 8, 9, 10
3) Name the elements in Period 2 that are metals.
Lithium and Beryllium
4) Name the elements in Period 2 that are nonmetals.
Boron, Carbon, Nitrogen, Oxygen, Fluorine, and Neon
*(Note: Boron is technically a metalloid, but it is often grouped with nonmetals in basic chemistry classes because it lacks metallic properties like shininess or conductivity. If your teacher distinguishes strictly between the three, move Boron to the metalloid category).*
5) Which elements are located in the following groups and periods?
a)
Group 4, Period 5: Zirconium (Zr)
b)
Group 2, Period 2: Beryllium (Be)
c)
Group 6, Period 6: Tungsten (W)
d)
Group 18, Period 1: Helium (He)
e)
Group 14, Period 5: Tin (Sn)
f)
Group 12, Period 4: Zinc (Zn)
g)
Group 1, Period 7: Francium (Fr)
h)
Group 16, Period 6: Polonium (Po)
i)
Group 17, Period 3: Chlorine (Cl)
j)
Group 11, Period 5: Silver (Ag)
6) For each of the following, label it as metal, nonmetal, and metalloid.
a) Poor conductor of electricity:
Nonmetal
b) Usually a solid at room temperature:
Metal (Most metals are solids; most nonmetals are gases).
c) Ductile:
Metal
d) Usually a gas at room temperature:
Nonmetal
e) Good conductor of heat:
Metal
f) Brittle:
Nonmetal (Metals are malleable, not brittle).
g) Chlorine:
Nonmetal
h) Semiconductor:
Metalloid
