Explanation:

To solve this, we use the periodic table's classification:

Step 1: Identify Metals

Metals are typically on the left/bottom of the periodic table, have metallic properties.

• $\ce{Tl}$ (Thallium): Metal (post - transition metal).
• $\ce{Ga}$ (Gallium): Metal (post - transition metal).
• $\ce{Bi}$ (Bismuth): Metal (post - transition metal).

Step 2: Identify Semimetals (Metalloids)

Semimetals have properties of both metals and nonmetals, lie along the “staircase” on the periodic table.

• $\ce{Sb}$ (Antimony): Semimetal.
• $\ce{Ge}$ (Germanium): Semimetal.

Step 3: Identify Nonmetals

Nonmetals are on the right - hand side, lack metallic properties.

• $\ce{Se}$ (Selenium): Nonmetal.
• $\ce{S}$ (Sulfur): Nonmetal.

Final Classification:

• Metal: $\ce{Tl}$, $\ce{Ga}$, $\ce{Bi}$
• Semimetal (metalloid): $\ce{Sb}$, $\ce{Ge}$
• Nonmetal: $\ce{Se}$, $\ce{S}$

Answer:

• Metal: $\ce{Tl}$, $\ce{Ga}$, $\ce{Bi}$
• Semimetal (metalloid): $\ce{Sb}$, $\ce{Ge}$
• Nonmetal: $\ce{Se}$, $\ce{S}$
