tetrahedral
They can't be for some purposes, but for others, adding electrons to a bond doesn't change the fact there are electrons there and as they are in the same/very similar places in comparison to other bonds or lone pairs, they may as well be one electron.
The balanced equation for the reaction between SO3 and H2O is: SO3 + H2O → H2SO4
The are two elements in SO3: sulfur and oxygen.
SO3 stands for Sulfur Trioxide.
I think it is acid, because there is a question that asks the acid site of SO3.
The molecular geometry of the AsO2- ion is bent (because of the lone electron pair with the central arsenic atom, making the O-As-O bond angle very obtuse) but its electron domain geometry is trigonal planar because there are three domains, with a 120 deg. angle between them.
Trigonal pyramid will be its molecular shape. It will have tetrahedral electron domain geometry.
The electron-domain geometry of PF6 is Octahedral, since the central atom Phosphorus has an electron pair geometry which is octahedral
Electron Domain is Tetrahedral Molecular Geometry is Trigonal Pyramidal
The electron-domain geometry of ClO4- is tetrahedral. It has four electron domains around the central chlorine atom, resulting in a tetrahedral arrangement.
The electron domain charge cloud geometry of ICI5 s usually positively charged. This is because the process involves the loss of electrons. The electron-domain charge-cloud geometry of ICl5 is octahedral.
3 bondings + 1 electron pair = 4 (electron domains)
