Es ist eine sehr giftige, bei Raumtemperatur gasförmige chemische Verbindung, Die Oktett-Regel nach Lewis besagt, dass die Atome im Molekül ihre Elektronen in Bindungen so teilen, dass sich um jedes Atom 8 Elektronen aufhalten. There are MANY exceptions to this rule, but it should be used as a general guide for creating Lewis structures. Notice that although this Lewis structure looks somewhat similar the one in (a), the two geometries for those answers are completely different because of the presence of the lone pair. The Lewis structure of a given chemical compound is crucial for knowing all the physical properties and chemical properties. This is sp 2 hybridization. PF5 will as a result of these characteristics will readily undergo hydrolysis even though this is an atypical property for nonpolar molecules. I also go over hybridization, shape and.
