Question

1. choose the best answer.

the three - dimensional shape of atoms in a molecule is ______ geometry.
molecular
theory
shape

1. choose the best answer.

______ theory is used to predict the shape of a molecule due to the repulsion between valence - level electron pairs.
molecular
geometry
vsepr

1. choose all that apply.

when determining the shape of a molecule, which three should be considered?
molecular geometry
the number of single, double, or triple bonds
vsepr theory
lewis structures

Explanation:

1. Molecular geometry is defined as the three-dimensional arrangement of atoms in a molecule.
2. VSEPR (Valence Shell Electron Pair Repulsion) theory predicts molecular shape by accounting for repulsion between valence electron pairs.
3. To determine molecular shape, Lewis structures show bonding/nonbonding electrons, the count of single/double/triple bonds affects electron domain repulsion, and VSEPR theory is the framework for using these to find shape. Molecular geometry is the end result, not a factor used to determine shape.

Answer:

1. O molecular geometry
2. O VSEPR

3)

• $\square$ the number of single, double, or triple bonds
• $\square$ VSEPR theory
• $\square$ Lewis structures
