Full Answer

Square pyramidal is a Lewis structure characterized by six equally spaced hybrid orbitals, each of which is angled at 90 degrees. The shape of the orbitals is octahedral and there is a single lone electron pair on the central atom. The other five atoms connect to the central atom. The spacing is such that, if lines were drawn, the figure would be a pyramid with a square base. An additional quality of square pyramidal structures is that they are polar.

Lewis structures are a method of visualizing the geometry and some properties of a compound. The first step in making a structure is determining the total number of valence electrons present in the compound and then drawing the skeleton of the structure. This shows the atoms present and the single lines that connect them, representing bonds. As the additional bonds are added, these are represented by lines between the atoms. The final step is distributing the remaining valence electrons to satisfy the octet rule for atoms, which states that most atoms must have eight total electrons.
