Sentences with phrase «with nitrogen atoms»

When it involves dating in singapore cultures Carbon - 14 is produced in the atmosphere when neutrons from cosmic radiation react with nitrogen atoms: 14 7 N + 1 0 n → 14 6 C + 1 1 H.

Yet most living things can't do any chemistry with the atmospheric form, two nitrogen atoms fiercely triple - bonded to each other.
The researchers were mixing organic nitrogen - rich compounds with nickel atoms and water.
The sensor itself is just slightly larger than a nitrogen atom, with a synthetic diamond to act as a substrate.
The models showed that thinner carbon nanotubes with a relatively high concentration of nitrogen would perform best, as oxygen atoms readily bond to the carbon atom nearest the nitrogen.

hydrogen cyanide A chemical compound with the formula HCN (meaning it consists of a bound atom of hydrogen, carbon and nitrogen).
Makemake is very much a Pluto analog — it has both methane and nitrogen detected on the surface, but unlike Pluto there is less nitrogen, so more methane atoms are in contact with each other.
