Solid nitrogen
- ... that solid nitrogen is an important component of the surfaces of Triton, a moon of Neptune, and of the dwarf planet Pluto?
ALT1:... that non-molecular forms of solid nitrogen have a higher energy density than any other non-nuclear material?- ALT2:... that under pressure, solid nitrogen and helium can form a birefringent van der Waals compound with formula He(N2)11?

ALT1 is not presently referenced but hopefully can be as it is a fact from the article lead which surprised me as a chemist.
ALT2 is an unusual compound, its discovery was reported I Nature.

- Actually ALT1 is referenced as it is stated lower down in the crystal structure section for cg-N and referenced by "Structural transformation of molecular nitrogen to a single-bonded atomic state at high pressures". I put it in the lead because it is exciting. Graeme Bartlett (talk) 12:38, 1 May 2016 (UTC)
- However the hook ALT1 is not strictly matching what the article says, as there are other non-molecular forms of solid nitrogen predicted to exist of unspecified energy density. I think that ALT2 is a bit too obscure for the average reader, with several unfamiliar words in it. So how about varying ALT1 to ALT3: Graeme Bartlett (talk) 12:49, 1 May 2016 (UTC)
- ALT3:... that one non-molecular form of solid nitrogen has a higher energy density than any other non-nuclear material?
- I have struck ALT1, deferring to the article's author on the accuracy of the alternative. I agree that ALT2 could be too obscure although I find it interesting. :) EdChem (talk) 12:54, 1 May 2016 (UTC) In light of recent additions, another option would be as follows.

- ALT4:... that solid nitrogen is used with liquid nitrogen to achieve more rapid cooling for sperm cryopreservation?
