What is the molecular geometry of the first molecule?
Number of Elektron Groups at Central Atom | Number of Surrounding Atoms | Molecular Shape |
---|---|---|
Any | 1 | linear |
2 | 2 | linear |
3 | 3 | Trigonal planar |
3 | 2 | bent |
What is the geometry of a molecule in this context?
The 3-dimensional space that a molecule occupies is called molecular geometry. It is determined using the central atom, the surrounding atoms, and electron pair. The Valence Shell Electron Pair Repulsion method (VSEPR), can predict the shape of most molecules.
Who also invented molecular geometry. The valence shell electron pair repellence (VSEPR), a method to determine the structure of covalent molecules, was proposed by Ronald Gillespie, a Canadian chemist, and Ronald Nyholm, an Australian chemist in a 1957 paper called "Inorganic Stereochemistry". According to the theory, the geometry around a given is determined by its geometry.
What is the molecular geometry for an abe3 molecule?

What are the five basic forms of molecules?
Molecular Geometries. VSEPR Theory describes five major shapes of simple molecules: linear and trigonal planar; tetrahedral; trigonal bipyramidal; and octahedral.

How do I calculate bond order?
- Draw the Lewis structure.
- Count the total number of bonds.
- Count the number of bond groups between individual atoms.
- Divide the number of bonds between atoms by the total number of bond groups in the molecule.
How do you predict shapes of molecules?
- VSEPR Rules:
- Identify the central atom.
- Count its valence electrons.
- Add one electron for each bonding atom.
- Add or subtract electrons for charge (see Top Tip)
- Divide the total of these by 2 to find the total.
- number of electron pairs.
- Use this number to predict the shape.
