or outer shell, electrons each included atom has, you can then count the number of bonding and non-bonding electron groups that encircle the central atom.These pairs are spaced around the valence shell in such a way as to achieve the furthest distance possible between ...

Video-Stimulated Recall Interviews in Pairs and Groups Video-stimulated recall involves recording an activity, here a digital animation, and then replaying the recording to the participants so that they can comment on aspects of interest [50]. These aspects can be chosen either by the researcher ...
For the problem under consideration, it is advisable to use the first of them since the van der Waals interaction implies almost only physical contact between the outer electron shells of the neighboring in the structure atoms excluding chemical bonding through valence electrons collectivization or ...
If the starting atom originally contains several valence electrons, then it can form multiple covalent bonds to different peripheral atoms. This is the basis for many simple covalent molecules like water H2O. This is also an example of a central atom containing non-bonding valence electron pai...
