for the molecule H3O+ provide a structure of the molecule and include the following:- the oxidation state of the central atom - the number of pi and/or stigma bonds - the molecular geometry - the electron geometry - the approximate bond angles

First let's find:
- the oxidate state of the central atom
The central atom is Oxygen. In this case, it's oxidation state number is -2.
- There are 3 sigma bonds.
- The molecular geometry is trigonal pyramidal
- The electron geometry is tetrahedral (There are 4 regions of electron density around the central atom)
- The approximate bond angles are 109.5 degrees.
