In the given system, A is the central atom which is surrounded by four B atoms and forms 4 covalent bonds. Ideally, this structure could correspond to a square planar molecular geometry. However, there are two lone pairs of electrons on the central atom A which must be considered in order interpret the electron geometry.
Thus the electron domain geometry around A is octahedral
Four electron shells cause both of them are on the 4th period.
