Study Notes

Key Concepts in Chemistry

  • The smallest number in the periodic table box is known as the atomic number, which represents the number of protons in an atom's nucleus.

  • An element is a pure substance that cannot be broken down into simpler substances by chemical means, defined by a unique atomic number and distinguished by its properties.

Mixtures

  • A homogeneous mixture is a mixture that has a uniform composition and properties throughout, meaning the individual components are not distinguishable and are evenly distributed.

  • A heterogeneous mixture contains visibly different substances or phases, where the components can often be seen and separated, resulting in a non-uniform composition.

Atomic Characteristics

  • The atomic weight (or atomic mass) of an element is the weighted average mass of an atom of an element based on the distribution of isotopes in a natural sample, usually expressed in atomic mass units (amu).
