S is a theoretical concept. Oh, I always advocate properly assigning formal charges to all atoms that need them, which is why I wouldn’t have upvoted your answer if only the first structure were shown ;). Electrons shared between two unlike atoms are counted towards more electronegative element. Ni­tro­gen dis­plays a con­sid­er­able num­ber of ox­i­da­tion states, from -3 to +5. The three oxygen atoms have a combined oxidation of -6, corresponding to their electromagnetic charge and the lone nitrogen has a charge, or oxidation number, of +5. But don't worry, I checked it and it clearly says that the covalency is limited to 4, not oxidation state! https://en.wikipedia.org/wiki/Dinitrogen_pentoxide, Oxidation State in Tetraaquadichlorochromium(III) chloride. µ”–EŠØ)©ÌÑKÎ¸%²AJÃt(+x²Í=ìt±‡�it^3øÔ`Ü�©ì3ê²)aSV;X‘—CB 0 (zero) represents an s orbital and 1 represents p orbital hence no D orbitals are there.
