2.1 Test Review

Metals

100

This material is the combination of copper and tin and led to new technologies being created around 3000 BC.

What is Bronze?

200

This metal was appreciated by such ancient civilizations as Egypt, Assyria, and the Minoans of Crete.

What is gold?

300

This refers to the gradual wearing away of a metal as a result of a chemical reaction in which the metal is changed into a metallic compound.

What is corrosion?

400

This refers to a substance's ability to be flattened into thin sheets by the application of intense pressure. Aluminum is an example of this.

What is malleability?

500

This is a substance's ability to be drawn or pulled into the form of a wire. Copper is an example.

What is ductility?

Ores

100

These were among the first metals to be discovered.

What were gold and silver?

200

This is a naturally occurring rock from which a useful metal or material is recovered.

What is an ore?

300

These two elements are readily able to combine with metals.

What are oxygen and silicon?

400

This is the process of removing minerals from the ground.

What is mining?

500

This is the process of converting an ore into a free, uncombined metal.

What is reduction?

Alkali Metals

100

Alkali metals are very good conductors of this.

What is electricity?

200

When sodium bonds with chlorine, this substance is created.

What is salt?

300

Despite being in the same column as the alkali metals, this element is NOT a metal.

What is hydrogen?

400

This alkali metal is the rarest one, is radioactive, and is usually found in uranium minerals.

What is francium?

500

This metal is used in fertilizers, detergents, and explosives.

What is potassium?

Alkaline Earth Metals

100

This alkaline earth metal has a low density, is lightweight, very strong, and stable over wide temperature ranges.

What is beryllium?

200

This is the most widely used alkaline earth metal.

What is magnesium?

300

This metal is essential for bone and tooth health.

What is calcium?

400

This metal absorbs X-rays well when a person ingests it, which helps to reveal medical conditions that might not have otherwise been discovered.

What is barium?

500

This element is radioactive and led to a treaty that required nuclear testing to be performed underground.

What is strontium?

Transition Metals

100

This is the most abundant transition metal in Earth's crust.

What is iron?

200

This metal is suitable for use inside the human body because it and its alloys resist corrosion caused by reactions with bodily fluids.

What is titanium?

300

This metal exists as a liquid at room temperature and is poisonous if inhaled or ingested.

What is mercury?

400

This element is common in our blood and makes us feel anemic and need medical attention when we don't have enough of it.

What is iron?

500

This metal has been chosen by scientists to be used in nuclear reactors and nuclear weapons due to its high potential energy.

What is uranium?
