About Lawrencium

The last one of the actinides, lawrencium is a radioactive metal which was discovered in the middle of the 1960s by a group of chemists of California, as well as by a group of Russian scientists from Moscow. This chemical element has got its name after Ernest Lawrence, an American inventor and nuclear scientist. So far, there are only a few atoms of this element have been created and were used only for scientific purposes. It is possible to obtain lawrencium from californium, in terms of a lab or a nuclear reactor. This chemical element is very dangerous for all living organisms on our planet.
