In the modern IUPAC nomenclature, the alkaline earth metals comprise the group 2 elements.

Famous quotes containing the word earth:

    If thou dost slander her and torture me,
    Never pray more; abandon all remorse;
    On horror’s head horrors accumulate;
    Do deeds to make heaven weep, all earth amazed;
    For nothing canst thou to damnation add
    Greater than that.
    William Shakespeare (1564–1616)
