Oxides

Nitrogen

Nitrogen has many several oxides, these are shown in the table below

NO₂ exists in equilibrium with N₂O₄

Phosphors

P₄O₁₀ and P₄O₆ are the most important of the oxides but there are also P₄O₇, P₄O₈ and P₄O₉ the later three are made by using a mixture of P(III) and P(V) centres the P(V) being from the P₄O₁₀ and the P(III) from the P₄O₆.
