There are six electrons in valence shell of oxygen, among these six electrons two electrons are unpaired and involved in forming covalent bond with hydrogen and carbon, while remaining 4 electrons in pair (i.e. 2s², 2px²) exists as lone pairs.

Steps: 1. Draw the Lewis structure. 2. Count the number of lone pairs and bond pairs on the central atom. (= areas of electron density). You can obtain a general shape from this number; this shape is called the electron-dot geometry. 3. Determine the number of lone pairs on the central atom.

In XeF2, XeF4, and XeF6, the number of lone pairs on Xe, is.
Determine whether bond angles are ideal (90o, 109.5o, 120o, 180o) or distorted due to lone pair – bonding pair repulsion. From the overall molecular geometry and the presence and arrangement of polar bonds (if any), determine if a molecule is polar.
This demo will convert a skeletal figure, provided by a drawing in the HTML5 SketcherCanvas component on the left, into a Lewis Dot Structure in the Canvas on the right. When you are finished drawing your 2D structure, click on the Get Lewis Dot Structure button to see the result.
The lone pairs will occupy the orbitals as far apart as possible i.e. on opposite sides of the octahedral shape according to the valence shell electron pair repulsion theory. The final result is a square planar arrangement of Xe-F bonds with lone pairs above and below.
XeF6 has 6 bond pairs and a lone pair which makes it's SN=7 (sp³d³) . VSEPR suggests PBP(Pentagonal Bipyramidal) geometry , but by electron diffraction experiments it is said to have “Octahedral” geometry with Fluorine atom on the corners.
