Lesson 15 and 16 Molecular Geometry

VSEPR stands for _______

In order to minimize repulsion, electron pairs around a central atom arrange themselves as _________as possible from each other.

• near

• far apart

• tight

• loose

Lewis structures represent the actual spatial arrangement of atoms in molecules.

• TRUE

• FALSE

Refers to the shape of the electron
