trigonal planar
Electron pair geometry considers both bonding and lone pairs of electrons around a central atom, while molecular geometry focuses solely on the arrangement of bonded atoms. This can lead to different geometries when there are lone pairs present; for example, in ammonia (NH₃), the electron pair geometry is tetrahedral due to one lone pair, but the molecular geometry is trigonal pyramidal. The presence of lone pairs affects bond angles and the overall shape of the molecule, resulting in distinct geometries.
tetrahedral due to the four area of electron density (two loan pair electrons and two bonded pairs).
Anything with six electron groups, keep in mind an electron group is a bonded atom or an electron pair, is an octahedral. Anything in an octahedral and a lone pair is the square pyramidal geometry. So all angles between the atoms are a little less than 90 degrees and the angle of the electron pair is greater than 90.

trigonal planar
The molecular geometry for a molecule with two electron groups and only bonded pairs is linear.
Electron pair geometry considers both bonding and lone pairs of electrons around a central atom, while molecular geometry focuses solely on the arrangement of bonded atoms.

The presence of lone pairs affects bond angles and the overall shape of the molecule, resulting in distinct geometries.
The presence of 1 lone pair in a molecule affects its molecular geometry by causing repulsion that pushes the bonded atoms closer together. This can lead to a distortion in the molecule's shape, often resulting in a bent or angular geometry.
This is a linear molecule.
The electron domain geometry of XeF2 is linear. This is because the central atom Xe has two bonded atoms (F) and no lone pairs of electrons, resulting in a linear molecular geometry.
The molecular geometry of a molecule with a tetrahedral pyramidal shape is called trigonal pyramidal. It has a central atom bonded to three atoms and one lone pair, resulting in a pyramid-like structure.
The molecular geometry of CS2 is linear. This molecule consists of a central carbon atom bonded to two sulfur atoms, and there are no lone pairs on the central atom. The bonds and atoms are arranged in a straight line, giving it a linear molecular geometry.
Electron pairs
In molecular geometry, bond length refers to the distance separating nuclei of bonded atoms in a single molecule.
tetrahedral due to the four area of electron density (two loan pair electrons and two bonded pairs).
The molecular geometry characterized by 109.5 degree bond angles is tetrahedral. This geometry occurs when a central atom is bonded to four surrounding atoms with no lone pairs on the central atom. An example of a molecule with this geometry is methane (CH4).
