Los metales de transición

Transition metals, located in the middle block of the periodic table, are known for their hardness, density, and low reactivity compared to alkali metals. They are excellent conductors of heat and electricity, making them essential in modern applications like electrical wiring. Most have high melting points, except mercury, which is liquid at room temperature. Transition metals are malleable and form compounds with distinct colors, such as copper oxides and salts. These metals are crucial for structural materials and include some of the most valuable elements.

Which of the following is a reason why copper is used for making pipes?

• It is a poor conductor of electricity.

• It is highly reactive with water.

• It does not react with water.

• It is the most expensive metal.

What is a common property of all transition metals?

• They have low melting points.

• They are highly reactive with air.

• They are good conductors of heat and electricity.

• They are all gases at room temperature.

Which metal is an exception to the high melting point characteristic of transition metals?

• Gold

• Mercury

• Copper

• Iron

What happens to copper sulfate when water is added?

• It becomes a gas.

• It turns bright blue.

• It turns red.

• It remains white.

Transition metals are important for which of the following applications?

• Building wooden structures

• Producing food

• Conducting electricity and transporting water

• Making plastic materials
