Identifying Metals, Nonmetals, and Metalloids on the Periodic Table

Which element among iodine, silver, and sulfur is the best conductor?

• All are equally good

• Iodine

• Silver

• Sulfur

Where are metals located on the periodic table?

• In isolated groups

• To the right of the zigzag staircase

• Only in the center

• To the left of the zigzag staircase

Which group of metals is known for being highly reactive?

• Noble gases

• Alkali metals

• Alkaline earth metals

• Transition metals

What makes alkali metals unique?

• Highly reactive and not found in their elemental form in nature

• Found as isolated atoms

• They are good insulators

• They are non-reactive

What are the properties of metals?

• Shiny, conductors, malleable, and ductile

• Dull, insulators, and brittle

• Non-reactive

• Gaseous at room temperature

What state are most nonmetals at room temperature?

• Gases or brittle solids

• Solid

• Plasma

• Liquid

Which group of elements is most reactive among nonmetals?

• Halogens

• Alkaline earth metals

• Noble gases

• Alkali metals

Why are noble gases stable?

• They are found in the center of the periodic table

• They are good conductors of electricity

• They are highly reactive

• Their outer energy level is full

What is the unique property of metalloids?

• Highly reactive with water

• Conduct electricity in a solid state only

• Are gases at room temperature

• Possess qualities of both metals and nonmetals

Which metalloid is used in computer chips?

• Sulfur

• Germanium

• Silicon
