The electron domain of sulfur trioxide (SO₃) consists of three regions of electron density around the central sulfur atom, each corresponding to a double bond with an oxygen atom. This results in a trigonal planar molecular geometry with bond angles of approximately 120 degrees. The absence of lone pairs on the sulfur atom further confirms that all three electron domains are involved in bonding. Thus, SO₃ exhibits a symmetrical arrangement of its electron domains.
tetrahedral
The electron domain of AsF3 (arsenic trifluoride) consists of four regions of electron density: three bonding pairs of electrons from the As-F bonds and one lone pair of electrons on the arsenic atom. This results in a tetrahedral electron geometry. However, due to the presence of the lone pair, the molecular geometry is trigonal pyramidal.
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.
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.
