Remember, the geometry of a molecule has to do with how many electron pairs AND lone pairs there are around the CENTRAL atom. Basically, count up the lines and the pairs of dots.
Notice that 'Xe' has 8 electrons in its valence shell, and 'F' has only 7.
When we put 4 'F' atoms around 1 'Xe' atom, each Flourine atom is going to want to 'share' one of Xenon's electrons so that it can have 8 electrons.
Also remember that when an atom shares electrons, it shares in pairs. Each shared bond has 2 electrons.
Now count up the number of electron PAIRS around the CENTRAL atom. We have 4 bonds (one with each Fluorine atom), and 2 lone pairs of of electrons bringing our count up to 12 electrons around Xenon, or 6 pairs total. (This violates the 'Octet Rule', but it's ok in this situation)
Here is a list of geometries according to the number of Electron Domains:
2 'ED's (electron domains) = Linear shape
3 'ED's = Trigonal Planar
4 'ED's = Tetrahedral
5 'ED's = Trigonal Bi-pyramid
6 'ED's = Octahedral
The electron-domain geometry of XeF4 would be Octahedral.

What is an example of a molecule with square planar geometry?
XeF4
What is the correct molecular geometry shape for XeF4?
octaedrique
Is XeF4 a tetrahedral?
No it is not a tetrahedral!
What is a characteristic of Euclidean geometry?
One main characteristic of non-Euclidean geometry is hyperbolic geometry. The other is elliptic geometry. Non-Euclidean geometry is still closely related to Euclidean geometry.
What is the electron geometry for OF2?
molecular geometry is bent, electron geometry is tetrahedral
What is an example of a molecule with square planar geometry?
XeF4
What is the correct molecular geometry shape for XeF4?
octaedrique
What is the molecular geometry of IBr4-?
Square Planar, Like XeF4
Which xenon compound is isostructural with ICl4?
XeF4 is isostructural with ICl4. Both compounds have a square planar molecular geometry with bond angles of 90 degrees and are considered isostructural due to their similar arrangement of atoms in the molecule.
Do XeF4 have a Lewis structure?
Yes, XeF4 has a Lewis structure. Xenon (Xe) is the central atom surrounded by four fluorine (F) atoms. Xenon has 8 valence electrons and forms 4 single bonds with the fluorine atoms, resulting in a square planar geometry.
What is the molecular shape of XeF4?
The molecular shape of XeF4 is square planar. Xenon (Xe) has 4 bonding pairs and 2 lone pairs around it, resulting in a square planar geometry.
Shape of XeF4?
XeF4 is square planar
Does XeF4 have dipole moment?
Yes, XeF4 has a dipole moment. Although the individual Xe-F bonds are polar due to the difference in electronegativity between xenon and fluorine, the molecule as a whole is nonpolar because of its symmetrical square planar geometry that cancels out the dipole moments of the individual bonds.
What is the bond angle of xef4?
90 degress
What is the formula for Xenon tetrafluoride?
The formula for xenon tetrafluoride is XeF4.
How many lone pairs on XeF4?
There are two lone pairs on XeF4.
What will XeF4 plus H2O give?
When XeF4 reacts with water (H2O), the result is the formation of xenon oxyfluoride (XeOF2) and hydrofluoric acid (HF). The balanced chemical equation for this reaction is: XeF4 + 2H2O -> XeOF2 + 4HF
