Question

the three - dimensional structure of molecules can be described in terms of the _, _, and relative _ of atoms in space. charge, size, dipole distances, angles, arrangements classification, charge, electronegativity arrangement, charge, dipole question 2 1 pts the vsepr theory model allows for the prediction of molecular shape base upon the arrangement of _ about the central atom in the lewis structure. nuclei neutrons electron pairs protons

Explanation:

For the first question, the three - dimensional structure of molecules is described by distances between atoms, angles between bonds, and relative arrangements of atoms in space. Charge and dipole are related to the electronic properties rather than the geometric structure directly. For the second question, VSEPR (Valence - Shell Electron - Pair Repulsion) theory predicts molecular shape based on the arrangement of electron pairs (bonding and non - bonding) around the central atom in the Lewis structure. Nuclei, neutrons, and protons are not what VSEPR is based on for shape prediction.

Answer:

1. B. distances, angles, arrangements
2. C. electron pairs
