Animals in Chile. The beautiful country of Chile is home to a variety of animals. Each species has adapted to each of the country's three main habitats consisting of the Andes Mountains, low coastal mountains, and the broad, fertile central valley.
Valence shell electron pair repulsion (VSEPR) theory is a model used, in chemistry, to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.SEPR theory therefore views repulsion by the lone pair to be greater than the repulsion by a bonding pair. As such, when a molecule has 2 interactions with different degrees of repulsion, VSEPR theory predicts the structure where lone pairs occupy positions that allow them to experience less repulsion.
1. Start from the Lewis dot structure and count areas of electron density around the central atom. In VSEPR a lone pair, a single unpaired electron and any bond (single, double or triple) each count as one area of electron density.For species with more than one central atom, treat each central atom separately.2.n VSEPR a lone pair, a single unpaired electron and any bond (single, double or triple) each count as one area of electron density.
