Study Notes
Atoms and Stability
- Atoms are the basic building blocks of matter, consisting of protons, neutrons, and electrons.
- Atoms can be considered unstable when they have an imbalance of protons and neutrons or if their electron configuration allows for reactivity.
- Unstable atoms may undergo radioactive decay or form chemical bonds with other atoms.
Molecules
- A molecule is formed when two or more atoms bond together chemically.
- Molecules can consist of the same type of atoms (e.g., Oâ‚‚) or different types (e.g., Hâ‚‚O).
Fire and Its Components
- Fire is a chemical reaction involving rapid oxidation, producing heat, light, and combustion products.
- The process of fire occurs when fuel reacts with oxygen, releasing energy in the form of heat and light.
Components Required for Fire
- Three essential components for fire to exist are:
- Fuel: Any combustible material that can be ignited, such as wood, paper, or gasoline.
- Oxygen: Typically sourced from the air, essential for combustion to occur.
- Heat: Sufficient temperature is needed to initiate and sustain the chemical reaction.
