What is electron pair geometry?
electron-pair geometry: arrangement around a central atom of all regions of electron density (bonds, lone pairs, or unpaired electrons) linear: shape in which two outside groups are placed on opposite sides of a central atom. molecular structure: structure that includes only the placement of the atoms in the molecule.
Is GeH4 tetrahedral?
The molecular geometry of GeH4 is tetrahedral with a symmetric charge distribution. Therefore this molecule is nonpolar.

Is electron geometry and molecular geometry the same?
The molecular geometry definition in chemistry is the arrangement of atoms in relation to a central atom in three-dimensional space. Electron geometry is the arrangement of electron groups. If all the electron groups are bonded, with no lone pairs, then the electron geometry and molecular geometry are the same.
What are the types of electron geometry?
Electron group geometries refer to the five geometries: linear, trigonal planar, tetrahedral, trigonal bipyramidal, or octahedral. If one or more of the bonding pairs of electrons is replaced with a lone pair, the electron geometry does not change but the the shape of the molecule is altered.

Which is an example of tetrahedral electron pair geometry?
Tetrahedral Electron Pair Geometry Examples: In methane, ammonia, water and hydrogen fluoride, the electron pair geometry is tetrahedral. All have four pairs of electrons about the central atom (C, N, O, or F). See graphic on middle left.
What is the electron pair geometry of methane?
In methane, ammonia, water and hydrogen fluoride, the electron pair geometry is tetrahedral. All have four pairs of electrons about the central atom (C, N, O, or F). See graphic on middle left. In methane, C has four bonds. In ammonia, N has 3 bonds and one lone pair of electrons.
How is the geometry of an electron pair determined?
The geometry is determined by minimizing the repulsions between electron pairs in the bonds between atoms and/or lone pairs of electrons as postulated by VSEPR theory.
