Faktoja:
- is a radioactive synthetic element
- twelve isotopes of lawrencium have been synthesized with lawrencium-262 being the longest-lived and heaviest, with a half-life of 216 minutes
- was produced by bombarding a three milligram target composed of three isotopes of californium with boron-10 and boron-11 ions
- the appearance of this element is unknown, however it is most likely silvery-white or gray and metallic
- if sufficient amounts of lawrencium were produced, it would pose a radiation hazard
- its symbol was formerly known as Lw
- is a synthetic element and has no known uses
