Webbför 2 dagar sedan · The shape of a molecule or ion is governed by the arrangement of the electron pairs around the central atom. All you need to do is to work out how many electron pairs there are at the bonding level, and then arrange them to produce the minimum amount of repulsion between them. You have to include both bonding pairs and lone pairs. WebbAnswer 1: Phosphorus is in group 15, so has 5 valence electrons; Cl is in group 17, so has 17 valence electrons All 5 electrons are used to form covalent bonds with Cl and there are no lone pairs This gives a trigonal (or triangular) bipyramidal shape: Phosphorus pentachloride or phosphorus (V) chloride Answer 2: trunk or treat trunk ideas
