Metals and Their Properties Quiz

Elements with similar properties are grouped together.

Substances made up of the same kind of particles.

Elements that are typically shiny, malleable, ductile, and good conductors of heat and electricity.

Elements that are typically dull, brittle, poor conductors of heat and electricity.

Grouping elements based on shared properties simplifies the study of their behavior.

The ability of a metal to be flattened into thin sheets without breaking.

The ability of a metal to be stretched into thin wires without breaking.

The ability of a material to withstand pulling forces without breaking.

The ability of a material to transfer heat or electricity.

Metals are good conductors of heat and electricity. Non-metals, generally, are not.

A naturally occurring inorganic substance found in the Earth's crust.

A mineral that contains a metal that can be extracted profitably.

The process of removing impurities from an ore.

Chemical reactions used to extract the pure metal from the ore.

The process of purifying a metal obtained from the ore.

A characteristic of metals that makes them shiny; their ability to reflect light.

Most metals are hard and can withstand pressure without deforming. However, some metals like sodium and potassium are soft enough to cut with a knife.

Metals generally have high density, meaning they are packed tightly with atoms. Exceptions are sodium and potassium which are less dense than water.

Non-metals generally have low melting and boiling points; they transition from solid to liquid and liquid to gas at relatively low temperatures.

Non-metals are generally brittle and break easily when hammered. They lack the ability to deform under pressure.

The ability of a material to transfer heat energy.

Materials that conduct heat well, like metals.

The ability of a material to transfer electrical energy.

Materials that conduct electricity well, like metals.

Materials that do not conduct heat or electricity well, like most non-metals.

Metals react with oxygen to form basic metallic oxides, which dissolve in water to form alkaline solutions.

A chemical reaction that releases energy in the form of light and heat.

A substance that dissolves in water to form an alkaline solution, turning red litmus paper blue.

A compound formed when a metal reacts with oxygen.

A test that uses litmus paper to determine if a solution is acidic or alkaline.

Metals generally have high melting points, while non-metals often have low melting points.

Metals tend to be dense and heavy, while non-metals are generally lighter.

Metals are malleable and ductile - they can be shaped and drawn into wires. Non-metals are brittle - they break easily.

Metals are good conductors of heat and electricity, while non-metals are poor conductors (insulators).

Most metals react with oxygen to form basic oxides. These oxides dissolve in water to form alkaline solutions. A red litmus paper turns blue in an alkaline solution.

Metals are typically solid at room temperature (except mercury).

Non-metals can be solid, liquid, or gas at room temperature.

Metals produce a ringing sound when struck, while non-metals do not.

Magnesium reacts with water and forms hydrogen gas, a colorless, odorless, and flammable gas.

Iron does not react with water under normal conditions. It reacts with acids (like diluted sulfuric acid) to produce hydrogen gas.

Zinc reacts with acids (like diluted sulfuric acid), similar to iron, producing hydrogen gas.

A chemical reaction that involves the release of heat energy is called an exothermic reaction.

Non-metal oxides are acidic in nature. For example, carbon dioxide dissolves in water to form carbonic acid, a weak acid.

The process of coating Aluminum cookware with a protective layer of aluminum oxide prevents further oxidation and protects the metal.

The vigorousness of a chemical reaction refers to how quickly or slowly it occurs. Some reactions are very fast, while others may take a long time to complete.

Metals react with oxidizing agents like oxygen to form metallic oxides.

A chemical reaction involving the release of hydrogen gas when metals are exposed to acids, like hydrochloric acid (HCl) or sulfuric acid (H2SO4).

Metals react with water under different conditions. Some metals like sodium and potassium react violently, some like magnesium react with boiling water, while others like copper don't react at all.

The experiment where metal like iron, magnesium, or zinc reacts with an acid in a test tube, generating hydrogen gas that is collected and identified by burning with a pop.

A reaction that is sped up by the presence of heat, indicated by an arrow with "Heat" written above it in a chemical equation.

A chemical reaction in which a metal reacts with water, releasing hydrogen gas and a metal hydroxide. An example is the reaction of magnesium with water.

Metals that react strongly with water, like sodium and potassium

Metals like copper, silver, gold, platinum, and mercury that don't react with water under normal conditions.

Non-metals that react with air, often stored in water to prevent the reaction.

Metals like iron and zinc react with dilute acids, such as hydrochloric acid (HCl) and sulfuric acid (H₂SO₄), to produce hydrogen gas (H₂) and a metal salt.

Metals like copper and mercury don't react with dilute hydrochloric acid but react with sulfuric and nitric acid without releasing hydrogen gas.

Non-metals generally don't react with acids. Some, like sulfur and phosphorus, react with hot, concentrated sulfuric or nitric acids but don't produce hydrogen gas.

Aluminum and zinc react with strong bases like sodium hydroxide (NaOH) or potassium hydroxide (KOH) to produce hydrogen gas and their respective salts.

The tendency of a substance to react with other substances to form compounds is called reactivity. More reactive metals readily form compounds and are often found in nature as compounds rather than in their pure form.

Highly reactive metals react readily with other substances and are often found in the form of their compounds. Less reactive metals are found in their native state (elemental form) because they don't form compounds easily.

Some food items containing acids, like citrus fruits, should not be stored in metal containers because the acid can react with the metal and form harmful compounds.
