What's the difference between s and n?

1, s is the third periodic element, and n is the second periodic element; 2. S in organic matter is usually bivalent, and N in organic matter is usually trivalent; 3. The highest valence S is not oxidized under non-acidic conditions, and the highest valence N is oxidized in any case.

4. The lowest price of S is strongly reducible and the lowest price of N is irreducible; 5. Simple substance S is solid under normal circumstances, while simple substance N is gas under normal circumstances; In the compounds of 6 and S, it is usually difficult to form stable free radicals, while in the compounds of N, it is easy to form free radicals, such as NO, NO2 and TEMPO.

7.s can form six bonds, but N can't form five bonds; 8. The elemental properties of S are active, while the elemental properties of N are extremely stable; 9. Generally, energetic substances may or may not contain S, but generally contain N; 10 and S-S bonds are generally stable, while N-N bonds are relatively unstable.

Of course, s and n still have a lot in common.

The hydrate corresponding to 1 and the highest valence oxide is a strongly oxidizing acid.

2. The nine integer valence states from the lowest price to the highest price all have corresponding compounds, and the valence states are relatively complete.

3.s can form tertiary sulfonium salt, and N can form quaternary ammonium salt.

4. Hydride has a bad smell and high toxicity.

5. They are all important elements of protein.
