Lawrencium

Radioactive lawrencium was named after Ernest Lawrence, the atomic physicist.

This synthetic metal does not occur naturally in the environment and does not have any applications due to its short half-life of merely three minutes. Lawrencium was created by bombarding californium with boron, and only a few of these atoms have ever been produced. Lawrencium would be hazardous if produced in large amounts, but this is improbable because of lawrencium's quick disappearing act!
