How many stable isotopes does nitrogen have? Chemistry Nuclear Chemistry Isotope Stability 1 Answer Meave60 Jul 3, 2018 Two. Explanation: #""^(14)"N"#, which makes up #99.6%# of a typical sample of nitrogen, and #""^(15)"N"#, which makes up #0.4%# of a typical sample of nitrogen. A synthetic isotope, #""^(13)"N"# has a half-life of #"9.965 min"#, and is therefore not stable. https://en.wikipedia.org/wiki/Nitrogen Answer link Related questions How do you determine isotope stability?
