Metals, Nonmetals, and Metalloids

Front

What are the main properties of metals?

Back

Metals are good conductors of electricity and heat, malleable, ductile, shiny, and typically solid at room temperature.

Front

What is a characteristic property of non-metals?

Back

Non-metals are generally brittle in solid form, not shiny, and poor conductors of heat and electricity.

Front

What are metalloids and where are they located on the periodic table?

Back

Metalloids have properties of both metals and non-metals and are found along the zig-zag line on the periodic table.

Front

Give an example of a metalloid and its properties.

Back

Silicon (Si) is a metalloid; it is a good conductor of electricity (semiconductor) and has a shiny appearance.

Front

Why are metals used for electrical wiring?

Back

Metals like copper and aluminum are used for electrical wiring because they are excellent conductors of electricity.

Front

What is the appearance of most non-metals?

Back

Most non-metals are dull in appearance and can be gases, liquids, or brittle solids.

Front

What is the significance of ductility in metals?

Back

Ductility refers to the ability of a metal to be stretched into a wire without breaking.

Front

How do the properties of metals differ from those of non-metals?

Back

Metals are typically shiny, malleable, ductile, and good conductors, while non-metals are dull, brittle, and poor conductors.

Front

What is an example of a non-metal and its properties?

Back

Sulfur (S) is a non-metal; it is yellow, brittle, and does not conduct electricity.

Front

What is the role of metalloids in technology?

Back

Metalloids, like silicon, are crucial in technology, especially in semiconductors and electronics.
