You can select more than one, or none, of these statements. Write the two Lewis structures land assign a formal charge to each atom. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Fluorine has 7 valence electrons, and will as a result want to form a . This still does not produce an octet, so we must move another pair, forming a triple bond: HCCH: no terminal atoms capable of accepting electrons, HCCH: form a triple bond between the two carbon atoms. The Lewis dot structure of Boron trichlortde enhances the idea about sharing electrons. One explanation is that the presence of available d orbitals in larger atoms allows these atoms to make more bonds; however, more modern chemical calculations have shown that d orbitals are not significantly involved in hypervalent bonding.

Because of their size and shape, fullerenes can encapsulate other molecules, so they have shown potential in various applications from hydrogen storage to targeted drug delivery systems. POF3 is slightly soluble in water. Standard Reference Data Act. Lewis structure of (SO3)-2, A: The resonance structures can be drawn as given below Note that phosphorus is a period 3 element, so it can keep more than 8 electrons in its last shell.
