    Which group of elements is normally obtained from the atmosphere in pure form?

    a) sulfur, phosphorus, oxygen, nitrogen
    b) magnesium, sodium, calcium, strontium
    c) flourine, chlorine, neon, argon
    d) flourine, chlorine, oxygen, nitrogen
    e) oxygen, nitrogen, neon, argon

    Answer:
    e) oxygen, nitrogen, neon, argon
    Oxygen Exists in the atmosphere as free or native gas.
    Elemental nitrogen is highly unreactive, largely because of its strong triple bond (almost as inert as the noble gases).
    Neon, argon are unreactive because they have completely filled s and p sub-shells.
    All these gases can be obtained by the fractional distillation of air.
