Metals
This material is the combination of copper and tin and led to new technologies being created around 3000 BC.
What is Bronze?
These were among the first metals to be discovered.
What were gold and silver?
What is electricity?
This alkaline earth metal has a low density, is lightweight, very strong, and stable over wide temperature ranges.
What is beryllium?
This is the most abundant transition metal in Earth's crust.
What is iron?
This metal was appreciated by such ancient civilizations as Egypt, Assyria, and the Minoans of Crete.
What is gold?
This is a naturally occurring rock from which a useful metal or material is recovered.
What is an ore?
What is salt?
This is the most widely used alkaline earth metal.
What is magnesium?
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?
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?
What are oxygen and silicon?
Despite being in the same column as the alkali metals, this element is NOT a metal.
What is hydrogen?
This metal is essential for bone and tooth health.
What is calcium?
This metal exists as a liquid at room temperature and is poisonous if inhaled or ingested.
What is mercury?
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?
This is the process of removing minerals from the ground.
What is mining?
This alkali metal is the rarest one, is radioactive, and is usually found in uranium minerals.
What is francium?
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?
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?
What is ductility?
This is the process of converting an ore into a free, uncombined metal.
What is reduction?
This metal is used in fertilizers, detergents, and explosives.
What is potassium?
This element is radioactive and led to a treaty that required nuclear testing to be performed underground.
What is strontium?
What is uranium?
