Tetrahedral VSPER model
Will a central atom with four bonding pairs always be considered tetrahedral? Are there any exceptions?

Re: Tetrahedral VSPER model
I think this shape is always regarding the central atom with 4 surrounding bonds.

Re: Tetrahedral VSPER model
A central atom with only four bonding pairs will have a tetrahedral shape. Exceptions start to arise when lone pairs get introduced. For example, a central atom with four bonding pairs and one lone pair will have a molecular geometry of seesaw. We'll most likely go in depth on this topic on Friday.

Re: Tetrahedral VSPER model
The tetrahedral shape always refers to a central atom with 4 bonding pairs, though if the central atom has lone pairs the shape is an exception and the molecular geometry will change.

Re: Tetrahedral VSPER model
A central atom with four bonding regions will always be known as a tetrahedral for its domain geometry BUT if there are lone pairs attached to the central atom this will change. Eventually we will cover molecular geometries which will allow us to name molecules with lone pairs attached to the central atom more specifically, so we won't refer to the structure just as a tetrahedral anymore, but something more specific according to the number of bonds and lone pairs of electrons.

Re: Tetrahedral VSPER model
will we cover shapes with lone pairs and bonding regions as well? like AX4E1 for example.

Re: Tetrahedral VSPER model
I believe it is always tetrahedral when 4 bonds surround the central atom, however, lone pairs could also play a role and change the shape.

Re: Tetrahedral VSPER model
I think its always a tetrahedral shape if there are four electron regions because they want to be as far away from each other as they can be which produces the tetrahedral shape.
