Key Terms

Electropositivity
The tendency of an atom to lose electrons and form positive ions.

Example: Sodium (Na) is highly electropositive.

Reactivity
The ability of a substance to undergo chemical reactions.

Example: Potassium reacts vigorously with water.

Cation
A positively charged ion formed when an atom loses electrons.

Example: Na⁺ is a sodium cation.

Periodic Table
A tabular arrangement of elements based on their atomic number and properties.

Example: The periodic table shows trends in reactivity.

Reactivity Series
A list of metals arranged in order of decreasing reactivity.

Example: Potassium is more reactive than copper.

Corrosion
The gradual destruction of materials, often metals, due to chemical reactions.

Example: Iron rusts when exposed to moisture.
