Phosphine dot cross diagram
WebJan 3, 2024 · These structural diagrams depict only the outer, or valence, shell electrons and are known as dot and cross diagrams. Electrons from different atoms use alternating symbols, usually a dot and a cross, to show which atom the electrons have come from. Let’s take a closer look at some compounds containing nitrogen.
