Naturally occurring nickel (²⁸Ni) is composed of five stable isotopes; ⁵⁸
Ni
, ⁶⁰
Ni
, ⁶¹
Ni
, ⁶²
Ni
and ⁶⁴
Ni
, with ⁵⁸
Ni
being the most abundant (68.077% natural abundance).^[4] 26 radioisotopes have been characterised with the most stable being ⁵⁹
Ni
with a half-life of 76,000 years, ⁶³
Ni
with a half-life of 100.1 years, and ⁵⁶
Ni
with a half-life of 6.077 days. All of the remaining radioactive isotopes have half-lives that are less than 60 hours and the majority of these have half-lives that are less than 30 seconds. This element also has 8 meta states.
