Study Notes
Particles Composing Matter
- Matter is composed of three main particles: atoms, ions, and molecules.
- Atoms are the smallest particles; examples include hydrogen and oxygen.
- Molecules form by bonding elements; common examples are water (H₂O) and sodium chloride (NaCl).
- Ions are charged particles, which can be either positive (cations) or negative (anions).
- Cations are formed by metals that donate electrons, while anions are formed by non-metals that accept electrons.
States of Matter
- The four fundamental states of matter are solid, liquid, gas, and plasma.
Properties of Matter
- Properties are classified as either intensive or extensive.
- Intensive properties are independent of the amount of matter present.
- Extensive properties depend on the quantity of matter.
- Matter can be categorized by how properties are measured: physical properties do not change composition, while chemical properties involve a change leading to a new composition.
- Pure substances maintain constant composition and are divided into elements and compounds.
Elements and Compounds
- The periodic table contains 118 elements; 92 are naturally occurring, and 26 are synthetic.
- Metals lose electrons, are malleable, and are good conductors of heat and electricity.
- Non-metals gain electrons, are brittle, and are poor conductors.
- Metalloids exhibit properties between metals and non-metals, often functioning as insulators.
Compounds
- Compounds consist of combined elements in fixed ratios and can only be broken down through chemical changes.
Types of Chemical Bonds
- Covalent bonds occur between two non-metals.
- Ionic bonds form between metals and non-metals.
Mixtures
- Mixtures consist of substances not chemically bonded and can be classified into three types: solutions, suspensions, and colloids.
- Homogeneous mixtures (solutions) combine a solvent and solute, resulting in a mixture that appears uniform to the naked eye (e.g., salt in water).
- Heterogeneous mixtures (suspensions) consist of distinguishable components that can be visually identified (e.g., oil in water).
