Study Notes
Key Concepts in Chemistry
- An alloy combines a base metal with other elements to enhance properties, improving strength, corrosion resistance, or other qualities.
- An anion carries a negative charge, resulting from an excess of electrons compared to protons; important in various chemical reactions and processes.
- An atom serves as the basic unit of matter, composed of protons (positively charged), neutrons (neutral), and electrons (negatively charged), forming the foundational structure of all substances.
