Study Notes
Chemistry Language
- Chemistry employs a unique language of rules and conventions to represent substances and atomic-level changes.
- Each chemical entity is assigned a specific identifier to facilitate understanding.
Chemical Symbols and Formulas
- Elements are represented by chemical symbols, which are one or two-letter abbreviations (e.g., Sodium as Na, Chlorine as Cl).
- Compounds are denoted by chemical formulas that illustrate their atomic composition (e.g., sodium chloride as NaCl).
- The naming of compounds follows a systematic approach, aiding in the identification of chemical substances.
Chemical Equations
- Changes in matter are represented using chemical equations, providing crucial information about the reactants, products, and conditions of a chemical reaction.
- These equations serve to concisely illustrate the processes and transformations occurring at the atomic level.
Elements in Chemistry
- There are approximately 120 known chemical elements.
- Out of these, 92 elements occur naturally in the Earth’s crust.
- The remaining elements have been artificially synthesized by scientists through methods like radioactive disintegration.
