What this model shows — and what it simplifies

Educational Model

The nuclear charge stays fixed at 76 protons, which is what defines Osmium.

Where do we see this in real life?

The electron count and measured properties of Osmium help determine how it bonds, reacts and is identified in chemical materials.
