Fun Fact: Some chemists regard lawrencium as the last of the actinides, and thus place it at the bottom right of the two rows of elements that are displayed separately from the others, as here. Others point out that because of chemical properties lawrencium�together with element 71, lutetium�should be placed in the leftmost column of the transition metals, underneath scandium (21) and yttrium (39). It was found in 1961 at the Lawrence Berkeley National Laboratory�the new name for the Berkeley Radiation Lab�and is named after its founder Ernest Lawrence.
