The valence shell electron-pair repulsion (VSEPR) model is used to predict the shapes of molecules and polyatomic ions. VSEPR is based on the idea that the “groups” or “clouds” of electrons surrounding an atom will adopt an arrangement that minimizes the repulsions between them.

Fluorine has 7 valence electrons. Which of the following is true of a fluorine molecule (F 2)? Which hybrid orbitals overlap in the C-N bond in Co (NH 2) 2? draw the lewis structure of azide (n₃⁻) and then determine the hybridization of the central atom. Which of the molecules below will be polar? CS 2, BF 3, SO 2, CH 3 Br.
Predict the structures of small molecules using valence shell electron pair repulsion (VSEPR) theory; Explain the concepts of polar covalent bonds and molecular polarity; Assess the polarity of a molecule based on its bonding and structure
VSEPR theory is used to predict the arrangement of electron pairs around central atoms in molecules, especially simple and symmetric molecules. A central atom is defined in this theory as an atom which is bonded to two or more other atoms, while a terminal atom is bonded to only one other atom.
