In the previous section, we discussed how to write Lewis structures for molecules and polyatomic ions. As we have seen, however, in some cases, there is seemingly more than one valid structure for a molecule. We can use the concept of formal charges to help us predict the most appropriate...

The common characteristic of these gases is that they all have eight electrons around their outermost shell or valence shell. This observation led to the other observation that elements lose or gain electrons to have eight electrons in their valence shell which is known as the rule of eight...
In some molecules, due to the arrangement of atoms, unequal sharing or distribution of electrons occur between the atoms of the molecule such that one end of the molecule becomes positively charged while the other end of the molecule becomes negatively charged. Such molecules are known as "Polar...

In addition, Loewenstein’s rule is respected, and local compensation of charges occurs by polyatomic arrangements involving Al and K atoms in well-defined configurations at the medium-range scale [4]. However, a model that only considers Loewenstein’s rule to explain the order–disorder of ...
Therefore, based on Walsh prediction [24], it appears that the linear p-block molecule holds up quite well for all B2N(−, 0, +) ions and the radical. This work has focused on a spontaneous symmetry breaking (SSB) [25,26,27] for B2N(−, 0, +) systems in view of ESP. 2....
