What this model shows — and what it simplifies
Educational ModelThe builder audits ordinary valence and electron counting on the connectivity the learner draws.
Where do we see this in real life?
Connectivity determines whether the same atoms make a medicine, solvent, fuel or toxic substance. Molecular editors use the same graph idea before advanced calculations begin.
