How many isotopes does lawrencium have
Lawrencium (103Lr) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes. The first isotope to be synthesized was Lr in 1961. There are fourteen known isotopes from Lr to Lr, and seven isomers. The longest-lived known isotope is Lr with a half-life of 11 hours. WebAmong the isotopes, 38 Ar and 40 Ar are stable and formed naturally. The remaining isotopes of argon are highly unstable and their half-lives are very short. Of the 26 radioisotopes of argon, the longest-lived radioisotopes are 39 Ar with a half-life of 269 years, 42 Ar with a half-life of 32.9 years, and 37 Ar with a half-life of 35.04 days.
