Won't it be Molecular geometry

yes

molecular geometry is right.

Yes, you are correct. The three-dimensional structure of the nuclei of atoms in a molecule or polyatomic ion is called molecular geometry. It describes the arrangement of atoms in a molecule and the spatial relationships between them. Molecular geometry is determined by factors such as the number and type of atoms and the arrangement of electron pairs around the central atom.

Yes, you are correct. The three-dimensional structure of the nuclei of atoms in a molecule or polyatomic ion is called "molecular geometry." Molecular geometry refers to the arrangement of atoms in a molecule and their relative positions in three-dimensional space. It describes the shape of the molecule and the angles between the atoms.

To determine the molecular geometry of a molecule or polyatomic ion, you can follow these steps:

1. Draw the Lewis Dot structure: Start by determining the Lewis Dot structure of the molecule or polyatomic ion by representing the atoms and their valence electrons. This provides a basic framework for understanding the bonding and electron distribution in the molecule.

2. Identify the central atom: Determine the central atom in the molecule or polyatomic ion. This is usually the atom that forms the most bonds.

3. Count the electron pairs around the central atom: Determine the number of electron pairs (both bonding and lone pairs) around the central atom.

4. Determine the electron pair geometry: Use the number of electron pairs to determine the electron pair geometry. This describes the arrangement of electron pairs around the central atom and is determined by the repulsion between electron pairs.

5. Determine the molecular geometry: After determining the electron pair geometry, consider only the atoms bonded directly to the central atom and ignore the lone pairs. This defines the molecular geometry, which describes the shape of the molecule.

By following these steps, you can determine the molecular geometry of a molecule or polyatomic ion and understand its three-dimensional structure.
