1. for each of the following, label as a metal, nonmetal, metalloid.

a. poor conductor of electricity
b. usually a solid at room temp
c. ductile
d. chlorine
e. semiconductor
f. silicon
g. malleable
h. usually a gas at room temp
i. cobalt
j. good conductor of heat
k. brittle
l. oxygen

Explanation:

Step1: Recall periodic - table knowledge

Use the periodic - table layout where groups are columns and periods are rows to identify elements.

Step2: Identify elements in groups and periods

a. Zirconium (Zr) is in group 4, period 5.
b. Beryllium (Be) is in group 2, period 2.
c. Tungsten (W) is in group 6, period 6.
d. Helium (He) is in group 18, period 1.
e. Tin (Sn) is in group 14, period 5.
f. Zinc (Zn) is in group 12, period 4.
g. Francium (Fr) is in group 1, period 7.
h. Polonium (Po) is in group 16, period 6.
i. Chlorine (Cl) is in group 17, period 3.
j. Silver (Ag) is in group 11, period 5.
k. Vanadium (V) is in group 5, period 4.
l. Platinum (Pt) is in group 10, period 6.
m. Aluminum (Al) is in group 13, period 3.
n. Bismuth (Bi) is in group 15, period 6.

Step3: Recall properties of metals, non - metals, and metalloids

Metals are good conductors of heat and electricity, malleable, and ductile. Non - metals are poor conductors, often gases or brittle solids at room temperature. Metalloids have intermediate properties like being semiconductors.

Step4: Label based on properties

a. Nonmetal (poor conductor of electricity).
b. Metal (usually a solid at room temp).
c. Metal (ductile).
d. Nonmetal (chlorine).
e. Metalloid (semiconductor).
f. Metalloid (silicon).
g. Metal (malleable).
h. Nonmetal (usually a gas at room temp).
i. Metal (cobalt).
j. Metal (good conductor of heat).
k. Nonmetal (brittle).
l. Nonmetal (oxygen).
