Cycloalkenes also start at three carbons and get increasingly stable as more are added, though their double bonds make their molecules plainer instead of tetrahedral.
Each lobe in that tetrahedral structure overlaps and bonds with one on an adjacent carbon atom creating a totally uniform, three dimensional network of carbon in every direction.
Phosphate is made up of one central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement, like a mini pyramid, and has a charge of minus 3 and is written PO43-.
