    KEY CONCEPTS

    • All matter, including mineral matter, is made of elements.
    • 8 to 10 elements account for most of Earth’s mass but the elements are distributed unevenly.
    • The Periodic Chart of the Elements orders elements by their atomic number and groups elements with similar properties.
    • Elements with similar properties may substitute for each other in minerals and many minerals have variable compositions.
    • Ionic, covalent, or metallic bonding are most common in minerals.
    • The kind of bonding affects mineral properties.
    • We describe mineral compositions by giving weight %s of the elements or oxides present.
    • Weight % values can be normalized to give chemical formulas.
    • Although 1000s of minerals are known, only a small number are common.
