    Atomic sentences have no connectives (~, &, v, ->, <->), and are usually represented by capital letters, sometimes using subscripts:


    A molecular sentence is composed of one or more atomic sentences and one or more connectives:
    (P & Q)
    (P v ~Q)
    ~(B1 -> B2) & B3

    Do you need to know more than that?
