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

1. for the following elements, list which is/are: mg, si, cl, cd, rb, pb, al, sb, ar, o, w, br, al

**note, some elements belong to more than one category.

1. metals:
2. nonmetals:
3. metalloids:
4. poor conductors of electricity:
5. gasses at room temperature:
6. solids at room temperature:
7. malleable and ductile:
8. liquids at room temperature:
9. have properties of both of metals and nonmetals:

Explanation:

Step1: Recall periodic - table knowledge

Use the periodic - table layout to identify elements by group and period.

Step2: Recall element properties

Based on known properties of metals, non - metals, and metalloids to classify elements.

1. Identify elements by group and period:

a. Hydrogen (already filled)
b. Zirconium (Zr)
c. Beryllium (Be)
d. Tungsten (W)
e. No element exists in group 18, period 1 (the first period has only H and He, He is in group 18 but not in period 1 as period 1 has 2 elements H and He)
f. Tin (Sn)
g. Zinc (Zn)
h. Francium (Fr)
i. Polonium (Po)
j. Chlorine (Cl)
k. Silver (Ag)
l. Vanadium (V)
m. Platinum (Pt)
n. Aluminum (Al)

2. Classify based on properties:

a. NM
b. M
c. M
d. NM
e. ML
f. ML
g. M
h. NM
i. M
j. M
k. NM
l. NM

3. Categorize given elements:

1. Metals: Mg, Cd, Rb, Pb, Al, W
2. Nonmetals: Cl, Ar, O, Br
3. Metalloids: Si, Sb
4. Poor conductors of electricity: Cl, Ar, O, Br, Si, Sb
5. Gasses at room temperature: Cl, Ar, O, Br
6. Solids at room temperature: Mg, Si, Cd, Rb, Pb, Al, Sb, W
7. Malleable and ductile: Mg, Cd, Rb, Pb, Al, W
8. Liquids at room temperature: None of the given elements are liquid at room temperature
9. Have properties of both metals and nonmetals: Si, Sb
