The process where iron reacts with oxygen and water to form iron oxide (rust).

A protective layer applied to iron to prevent direct contact with air and water, thus preventing rusting.

Applying a thin layer of zinc to iron to prevent rusting. Zinc acts as a sacrificial metal, corroding instead of iron.

A method of preventing corrosion by electroplating a thin layer of chromium onto metal surfaces.

An electrolytic process used to enhance the protective oxide layer on aluminum, making it more resistant to corrosion.

A material formed by mixing two or more metals, often improving the properties of the resulting material.

A commonly known alloy consisting of iron and carbon, known for its strength and corrosion resistance.

A process of intentionally mixing metals to improve their properties, like strength, corrosion resistance, or malleability.

A pure substance made up of only one type of atom. Examples include gold, iron, and oxygen.

A substance made up of two or more different elements chemically combined in a fixed ratio. Examples include water (H2O) and salt (NaCl).

A substance composed of more than one type of particle. Examples include air, saltwater, and soil.

Substances made up of only one type of particle. They can be either elements or compounds.

Elements that easily lose electrons to form positive ions. They are generally good conductors of heat and electricity, and have a shiny appearance.

Elements that tend to gain electrons to form negative ions. They are generally poor conductors of heat and electricity.

Metals have 1, 2, or 3 electrons in their outermost shell, making it easy to donate electrons to achieve a stable electron configuration. Non-metals have 5, 6, or 7 electrons in their outermost shell and easily gain electrons to achieve a stable octet configuration.

Metals are generally good conductors of heat and electricity, malleable, ductile, lustrous, sonorous, and have a high density. Non-metals are generally poor conductors of heat and electricity, not malleable or ductile, not lustrous, not sonorous, and have a low density.

The hardest known natural substance, made entirely of carbon atoms.

A list that ranks metals based on their tendency to lose electrons, indicating their reactivity.

A chemical reaction where a more reactive metal displaces a less reactive metal from its compound.

The characteristic shininess of a metal.

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

The ability of a metal to be drawn into long, thin wires.

Metals with 1-3 valence electrons that readily lose electrons to form positively charged ions (cations).

Non-metals with 4-8 valence electrons that easily gain electrons to form negatively charged ions (anions).

A chemical reaction where a substance loses electrons, resulting in an increase in its oxidation state.

A type of chemical reaction where a more reactive element displaces a less reactive element from a compound.

Metals react with water to form metal hydroxides and release hydrogen gas, except for metals below hydrogen in the reactivity series.

The process of extracting metals from their ores, which involves various techniques depending on the metal's reactivity.

The process of purifying metals by removing impurities, such as using electrolysis for copper refining.

A mnemonic device to remember the order of the reactivity series: * "Cat(K)arina(Ca) Wants (W) Cars (Cr), L(Li)ike (Li) Old (Al) Ford (Fe) Just (Zn) To (Ti) Get(Ga) Her(H) One(1) Because (Ba) Silver(Ag) D(Cu)ad(Hg) Did(Mn) Not (Ni) Ask"**
