See-Saw Shape

Hello!
Can someone explain what the see-saw shape is please? Is it another name for something in our notes? I know it involves a lone pair, but I cannot conceptualize how it looks like a see-saw.

Thanks!

Hello! I believe that see saw shape is one in which the central atom has 5 regions of electron density, 4 being bonds between the atoms and the 5th being the lone pair. For example, in the Lewis structure for TeCl(subscript 4), Te is the central atom and when all formal charges equal 0, Te has five regions of electron density, three single bonds, one double bond and one lone pair, thus it is see saw shape. Hope this helps!

Going off of Melissa, the lone pair on the central atom wants to occupy as much space as they can, so they push the other atoms in the opposite direction, condensing the atoms to each other to make a see saw structure.

Here is a visual of an example of a molecule with a see-saw shape.
