Definition of an atomic sentence

[Matthias765]

Can somebody please tell me what is the definition of an atomic sentence and the definition of a molecular sentence? Thanks

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

P
Q
B₁
B₂
etc.

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

Do you need to know more than that?

Thanks for telling me about atomic and molecular sentences, that's all I need to know for now.
