Question

Which theory describes the way atoms are arranged within a molecule?

A. The scientific theory
B. The VSEPR theory
C. The Bohr atomic model
D. The atomic theory

Answer 1

B. The VSEPR theory

Step-by-step explanation:

The valence shell electron pair repulsion theory describes the way in which atoms are arranged within a molecule.

• If an atom is bonded to two or more other kinds of atoms as in many covalent molecules and ions, the shape of the system is determined by the geometry of the bonds around the central atom.
• The variations in the bond angles of such molecules and ions can be explained by the valence shell electron pair repulsion model and hybridization.
• All electron pairs will orient themselves in such a way as to minimize the electrostatic repulsion between them.
