Square pyramidal is a molecular shape that results when there are five bonds and one lone pair on the central atom in the molecule. 2 bonds/ 3 lone pair bond angles: 180° DSP3 Hybridization. In this case, the central atom sits above a base of four neighbors; those four positions form a square plane together. The exponents on the subshells should add up to the number of bonds and lone pairs. Clearly show your method. $\begingroup$ By square planar, I'd assumed the structure of XeOF4 and that ceased me to think of other types of square pyramidal.
