Ion-exchange and solvent extraction techniques are used … 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. Lawrencium is the last actinide. Authors considering the subject generally consider it a group 3 element, along with scandium, yttrium, and lutetium, as its filled f-shell is expected to make it resemble the other 7th-period transition metals. In the periodic table, it is to the right of the actinide nobelium, to the left of the 6d transition metal rutherfordium, and under the lanthanide lutetium with which it … ttt writing

"WebElement 103, lawrencium, was discovered in 1961 by Ghiorso and co-workers [GHI61]. They produced a new 8.6-MeV alpha-emitting isotope with a 8±2 second half- life in the reactions ofnB and10B with252Cf. This isotope was later assigned to258Lr. Since that time, a total of ten isotopes have been produced and identified, (See Table I). " - How many isotopes does lawrencium have
