Electron Geometry and Lone Pairs

Description

Electron geometry and lone pairs help explain why molecules take specific shapes. The arrangement of electron groups around a central atom controls the molecular geometry. Valence electrons form bonding pairs, which sit mainly between bonded atoms, or lone pairs, which belong to one atom only.

Transcript

Molecules have characteristic shapes that are important for their functions.

Any diatomic molecule, such as molecular oxygen or hydrogen, is always linear.

As the number of atoms increases, the arrangement of electrons around the central atom influences the shape of the molecule, allowing it to bend and form more complex structures.<...
