Hi, this might be a silly question, but does anyone know why an octahedral is an octahedral? Where does the 8 from "octa-" come from if there are only 6 atomic orbitals?

There is a total of eight sides if you draw two pyramids, each with four sides.

An octahedron is a shape that consists of two pyramids who share a base. If you look at the molecule shape of an octahedral, it resembles the shape of an octahedron. Hence the name.

Thank you for asking this because you weren't the only one wondering! All the responses are helpful.

Although it is a six bond geometry it is called octahedral because when connected and focusing on the geometry, there are eight faces, therefore having the prefix octa-.

You must think about it's shape in a 3-Dimensional form, then you can see how there are 8 different sides in its shape.

It's because it is in the 3D form not 2D.
