    Study Notes

    Compounds and Their Definitions

    • Binary compounds consist of two elements.
    • A compound is formed from two or more elements that chemically combine.
    • The law of definite proportions states that a compound always contains the same elements in the same mass proportions.

    Molecular Structure and Components

    • A molecule is the smallest unit of a compound that retains its chemical properties.
    • The subscript in a chemical formula indicates the number of atoms of the preceding element in the compound.

    Examples and Applications

    • The formula for table salt is NaCl, which exemplifies the law of definite proportions as it is always NaCl.
    • Electrons are the subatomic particles involved in chemical bonding, as they are exchanged or shared during interactions.
    • Pure gold is categorized as an element, whereas pure water is classified as a compound.

    Identifying Atoms and Compounds

    • A molecule of rust (Fe2O3) contains five atoms.
    • MgCl2 is correctly named magnesium chloride.
    • The compound N2O is best referred to as dinitrogen monoxide.

    Composition of Specific Compounds
