Transition Metals

Transition metals, located in the middle 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 and plumbing. Most have high melting points, with mercury as an exception. Transition metals are malleable and form colorful compounds and salts. They are crucial for structural materials and include some of the most valuable elements.

Which of the following is a reason why copper is used in water pipes?

• It does not react with water.

• It is the most expensive metal.

• It is a poor conductor of electricity.

• It is highly reactive with water.

What is a unique property of mercury among transition metals?

• It is the hardest metal.

• It is liquid at room temperature.

• It has the highest melting point.

• It is the most reactive metal.

Why are transition metals considered invaluable in modern technology?

• They have low melting points.

• They are highly reactive.

• They are poor conductors of electricity.

• They are good conductors of heat and electricity.

What happens to anhydrous copper sulfate when water is added?

• It turns red.

• It remains white.

• It becomes brilliant blue.

• It turns green.

Which of the following is a characteristic of transition metal compounds?

• They are always colorless.

• They form only one type of compound.

• They often have characteristic colors.

• They are always gaseous.
