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

o. hydrogen
p. germanium
q. fluorine
r. potassium
s. tin
t. nitrogen
u. cadmium
v. plutonium
w. strontium
x. argon
y. poor conductor of electricity
z. usually a solid at room temp
aa. ductile
bb. semiconductor

dd. usually a gas at room temp
ee. good conductor of heat
ff. brittle

Explanation:

Step1: Recall periodic - table knowledge

Elements in the periodic table are arranged in groups and periods. Metals, non - metals, and metalloids have distinct properties.

Step2: Identify elements by group and period

a. Calcium (Ca) is in group 2, period 4.
b. Iodine (I) is in group 17, period 5.
c. Krypton (Kr) is in group 18, period 4.
d. Indium (In) is in group 13, period 5.
e. Iron (Fe) is in group 8, period 4.
f. Gold (Au) is in group 11, period 6.
g. Lithium (Li) is in group 1, period 2.
h. Titanium (Ti) is in group 4, period 4.
i. Silicon (Si) is in group 14, period 3.
j. Fluorine (F) is in group 17, period 2.
k. Calcium (Ca) is in group 2, period 4.
l. Sodium (Na) is in group 1, period 3.
m. Zinc (Zn) is in group 12, period 4.
n. Oxygen (O) is in group 16, period 2.

Step3: Classify elements as metal, non - metal, or metalloid

o. Hydrogen is a non - metal.
p. Germanium is a metalloid.
q. Fluorine is a non - metal.
r. Potassium is a metal.
s. Titanium is a metal.
t. Nitrogen is a non - metal.
u. Cadmium is a metal.
v. Plutonium is a metal.
w. Strontium is a metal.
x. Argon is a non - metal.
y. Non - metals are poor conductors of electricity.
z. Metals are usually solids at room temperature.
aa. Metals are ductile.
bb. Metalloids are semiconductors.
cc. Metals are malleable.
dd. Non - metals are usually gases at room temperature.
ee. Metals are good conductors of heat.
ff. Non - metals are brittle.
