Re: H3O+
H3O+ has tetrahedral orbital geometry because it is sp3 but has a trigonal pyramidal molecular geometry due to the one lone pair and the 3 atoms.
Re: H3O+
Hi!
H3O+ has a molecular geometry of tetrahedral, since there are 4 regions of electron density surrounding the central O atom (3 Hydrogens and 1 lone pair of electrons). The VSEPR shape would be trigonal pyramidal.

What does this mean in terms of bond angles?

Re: H3O+
This molecule is tetrahedral because it has four regions of electron density, one being a lone pair.

Re: H3O+
H3O+ is has an electron arrangement tetrahedral because there are 4 regions of electron density. However, the shape of H3O+ is trigonal planar because there are 3 bonds and 1 lone pair in H3O+. Be sure when looking at a molecule that you differentiate whether or not you are looking for shape or electron arrangement.

Re: H3O+
H30+ is tetrahedral since the O is bonded to 3 hydrogens and has a lone pair which makes the molecule have 4 electron densities. Since there's one lone pair the shape would be trigonal pyramidal.

Re: H3O+
H3O+ is tetrahedral because when drawing the lewis structure, there are a total of 8 electrons, and so oxygen should have 3 bonds (to hydrogens) and then one lone pair, which means there are four regions of electron density about the central atom, which means the molecular geometry is tetrahedral, but the shape is trigonal pyramidal.

Re: H3O+
The Lewis structure has 8 electrons, and when drawing the Lewis structure there are three bonds to the oxygen, with one lone pair. So there are 4 electron domains, so the molecular geometry is tetrahedral. But one electron domain is a lone pair, so the actual shape is trigonal pyramidal.

Re: H3O+
H3O+ is tetrahedral because it has 8 total valence electrons, so there must be a bond between each of the 3 H atoms and the O, leaving a lone pair on the O.
